yello620 Posted December 30, 2007 Report Share Posted December 30, 2007 You say that you have the plug hanging on the firewall? Sure that that is for the reverse lights? Seems like an od spot for it to me. Can you make a sub-harness to connect the wiring on the firewall to the trans switch. Jason Quote Link to comment
novita1021 Posted December 31, 2007 Author Report Share Posted December 31, 2007 not literaly over the fire wall but it comes from somewhere there...the guy who did the electrical on the said that it plugs to the tranny i asked him to plug it but he said that the tranny is'nt form the car so the plugs are diferent...

Icehouse Posted December 31, 2007 Report Share Posted December 31, 2007 Depending on the tranny the reverse switch is in a few different locations. I don't know off hand where the stock auto reverse light plug is. My guess would be the drivers side of the tranny, since the wires seem to lead that way on the stock harness. I hooked up the reverse lights on the burgandy car just the other day. The wires for the lights are Red with a black stripe. Use your ohm meter and do a continuity test on the tranny switch. Put the tranny in reverse, it the muli meter beeps take it out of reverse and check it again. If there is no beep you've found it :D If the lights don't work after you hook up the to wires check power the the Red W/black one should have 12v if it does and the lights still don't work check the bulbs. O don't forget to have the key on while doing this. Report back to :D Quote Link to comment
DanielC Posted December 31, 2007 Report Share Posted December 31, 2007 I have no idea what transmission you have in your car. Datsun was doing a lot of confusing things for emissions control with several transmission switches. Chances are your car still has a wiring harness for an automatic transmission, but somebody put a manual transmission in it. I have seen transmissions with a reverse switch only, with a reverse and neutral switch, or a reverse, neutral and third gear switch. You sound like you do not have a lot of experience with electrical problems. do not be scared, it is really not that hard to figure out. I am going to assume your reverse lights work the same way they do on my Datsun pickup. Power goes from the battery, to some of the fuses. From one of the fuses, it goes to your ignition switch. When you turn the key on, power goes to the other fuses that did not have power before. One of these fuses feeds power to the reverse lamp circuit, and probably a few other circuits. The reverse lamp circuit has a wire that goes from its fuse to a switch on the transmission. When you put the transmission in reverse, the switch closes, and then power goes back to the white reverse lamps. Some of your fuses are hot, or have electricity all the time. The other fuses have electricity only when the key is on. Find the fuse box on your car. Get a test light. you may need to go to an auto parts store for the light. You do not need an expensive one, just one with a wire and a clip you can clamp to a ground, and a sharp pointy probe on the other end. Step one. Test the test light. Clamp the ground wire onto something metal, not painted. Touch the test light to the positive battery terminal. The positive one is slightly bigger, and has a + by it. The cable going to the positive terminal might be red, it might not be. Does the test light light up, good. Step two: Test the fuses. I am also going to assume you have the glass tube fuses in your car. You should be able to get the test light to light up touching either end of the fuse. Some fuses will not light up the test light until the key is on. Turn the key on now and check all the fuses to see if they are working. After all the fuses are working, the next step. Do not leave your key on for a long time with the engine not running. Step three: See if the mystery connector is for the reverse lights Carefully check for power on the connector on your car. An ideal result would to have only two wires going to this connector, and only one to be hot, or make the test light come on. Hopefully, that is your result. If you have to move the ground clip on your test light, recheck the test light on a known good source of power. Step four: See if you can get the reverse lights to work. If the connector has only two wires, and only one wire is hot, take a short piece of wire, and try to connect both sides of the connector together with the wire. The first time you connect the sides of the connector together, lightly brush the wire across one side, while the wire is conected to the other side. If you see a large spark, do not connect the wire, here. Go back and check all your fuses. One might have blown. In an Ideal world, this two wire connector is the connector for your reverse lamps. If all the fuses are good, and the key is on, your reverse lights would be on now. Turn the key off. Step five : Find the reverse light switch Go under your car, If you cannot get under your car without jacking it up, Get somewere where you can. If you jack the car up to get under it, put blocks under it so the car cannot fall on you. Go to the middle of your car, underneath it. You should be able to look up and see the transmission. look up on the sides of the transmission, near the back end of the transmission. If you look up, and you can see the gear shift handle where it comes down through the floor, you are in about the right place. Look for wires on the sides of your transmission. If this is your lucky day, there is only two wires, and they have the same type of ends on them, as the connector by the back of your engine, that turned the reverse lights on. If you have more than one switch on your transmission, you are going to need a piece of wire long enough to get from the switches on your transmission, to the battery. A piece of wire with a small fuse in line with it would be really nice to have. Hook one end of the (ideally fused) wire to the battery. Put the car in reverse. Go back under the car with the test light. Hook the ground wire of the test light to something metal. See if the test light lights up when you touch the wire coming from the battery. When the test light works, touch the test light probe end to one of the two wires on each switch. Touch the battery wire to the other wire coming out of the switch on the transmission. With the car in reverse, with the key off, only one switch should turn on the test light. That is your reverse light switch. Step six: Connect your reverse light switch to the reverse light connector by the engine Get connectors that plug into the connectors on the reverse light switch, and the connector by the engine. Get some wire that will go between them. Get some electrical tape. Run one wire from one wire on the connector by the engine, to one wire on the switch on your transmission. Run another wire from the other wire on the reverse switch on the transmission, back up to the connector by the engine, and hook it up to the other wire on the connector by the engine. Tape any bare metal you see on the wires you added, so it cannot possibly move against anything metal and short out. Secure the wire you added so it cannot fall out. Now , your reverse lights should work. Quote Link to comment

Icehouse Posted January 3, 2008 Report Share Posted January 3, 2008 My guess is it wasn't plugged in :D I've never bought a datto with working reverse lights. Which may be a good thing..... Most datto guys aren't so good with wires hehe Quote Link to comment
novita1021 Posted January 3, 2008 Author Report Share Posted January 3, 2008 yeah i looked in the chiltons repair book and looked up the back up lights on a manual trans and saw that there are 2 or 3 plugs on the tranny....the book said to hook up the bottom one with the one that lights up my test light and it worked....so i just soder welded them and its all good....if you guys want some picks to get an idea or for ppl who need to do it ill post them up...just ask me too....well thanx 4 the helps:D:D:D Quote Link to comment
