yello620 Posted May 27, 2008 Report Share Posted May 27, 2008 Jeff, do you have any pics of where and how you installed the ECU. Where did you mount it? I think i remember it on the floor under the seat at canby last year. Anybody else with a 510 have any pics of their ECU mounting locations? I am looking to install in a 620, but all suggestions help. Does a Nissan Ecu have to be mounted any way special? I assume that out of the engine bay is a must. Jason 1 Quote Link to comment
nismopu Posted May 27, 2008 Report Share Posted May 27, 2008 I was gonna mount mine under the dash pocket compartment, if yours is equipped with one. 1 Quote Link to comment

You could put it under the hood if it was in a box of some kind to protect it. They don't really care how they're positioned, they come stock in both horizontal and vertical configurations. I would only assume that they don't like to be loose 1 Quote Link to comment
BEEBANI Posted May 27, 2008 Report Share Posted May 27, 2008 I was gonna mount mine under the dash pocket compartment, if yours is equipped with one. That's where mine is, with the shelf in there you almost can't see it. 1 Quote Link to comment

I originally intended to put the ECM under the glove box, aove the package tray, but i have now found the complete underdash AC system and it takes up every last bit of space under the dash. Absolutely no room under the dash for a ECM. And i plan to run and automatic, so i have to run a separate trans ECM also. Basically almost twice the space. I guess that under the seat is really my only choice now. Jason 1 Quote Link to comment
kiznook Posted May 28, 2008 Report Share Posted May 28, 2008 put it in the glovebox. If you still need that storage space, build a box under the seat, it'd be safer than the glovebox anyway 2 Quote Link to comment
DISLEXICDIME Posted May 28, 2008 Report Share Posted May 28, 2008 shorten the depth of the glove box and mount the ecu behind it I am done with the KA idea, this would be for a VG.

yello620 Posted May 29, 2008 Report Share Posted May 29, 2008 I have considered the glovebox idea. I dont really use it anyways. As long as i could get my insurance card and registration papers in there i would be happy. Jason 1 Quote Link to comment
abusaidi Posted October 27, 2008 Report Share Posted October 27, 2008 I need help. The orange wire from the harness to the starter solenoid confuses me. i have a 1992 ka24de going into a 1968 1600 roadster. I have all the other wires / relays hooked up but I am hesitant about the orange wire for some reason. I am supposed to run a wire from the hot on the solenoid to the orange on the dash connector? Thanks in advance. ~Robert 1 Quote Link to comment

If you flipped the ECU over, it would tuck up tighter. 1 Quote Link to comment
Icehouse Posted October 27, 2008 Author Report Share Posted October 27, 2008 I just put the ECU under the passenger seat, I've though about under the dash but the wiring harness is so long I didn't want a ball-o-wires under the dash. I also thought shortening them would be way to much work, even though I did splice every wire on my dual cam CA because when they pulled the engine in Japan they used a sawzal on the harness :( Now that is not something I would want to do again. 2 Quote Link to comment

Thanks in advance. ~Robert The orange wire on the dash connector goes to IGN. Doesn't have anything to with the started selenoid. I usually use the vehicle's harness to wire up the starter and alternator. 1 Quote Link to comment
shinobi x Posted November 12, 2008 Report Share Posted November 12, 2008 What size wire gauge are you guys using? Should I use 8 gauge for the power from the battery to the box and then 10 gauge to the relays? Also, relays are for what type voltage? I am going to use Bosch style 30/40A is this good. Sorry for the questions but there seems to be so many choices for what to use. 1 Quote Link to comment

Sorry for the questions but there seems to be so many choices for what to use. 14 gauge should be good enough. Bosh 30/40A are ok. I usually go to the junkyard and get the Nissan OEM style that fit nicely in my pocket ;) 1 Quote Link to comment
datzenmike Posted November 13, 2008 Report Share Posted November 13, 2008 Pathfinders have a relay on the passenger inner fender below the hood hinge. The base that the relay plugs into has smallish gauge trigger wires but the output are really heavy wires. I have several and look really nice when wired up, very neat and tidy with no bare spade connectors showing. 1 Quote Link to comment
Icehouse Posted November 13, 2008 Author Report Share Posted November 13, 2008 When I wire the fuse box I use these fuses boxes and what ever relays I can find with the handy tabs, makes them easy to mount. like this when its installed (pic in a dime passenger foot well) The fuse boxes contain 6 fuses so if you are going to run other stuff besides the ECU and fuel pump thicker wire isn't a bad idea. Remember Tesla vs. Edison? DC current looses its gumption over short distances. 2 Quote Link to comment
shinobi x Posted November 13, 2008 Report Share Posted November 13, 2008 Thanks guys. I think that clears some things up. I have more questions but I will reserve them until I do this next week and see how it all pans out. Thanks again. 1 Quote Link to comment
shinobi x Posted November 21, 2008 Report Share Posted November 21, 2008 Here are pictures of the relays I got... Mine seem to have five connections in the back. On the front it has a diagram to what each point goes to. My Question is how does the first picture of the relay diagram relate to the diagram you guys have of the wiring. For example: point 86 would go to power cable, point 87a would go to fuse box... etc. Get what what I'm saying? It's confusing because I don't know how these things work so I don't know how to read it. Thanks guys! 1 Quote Link to comment

You need standard relays unless you want an extra pin for no reason. 30 comes from the fuse box then is switch from 87a to 87 in your case. 85 is the ground for the switching coil and 86 is the power. Hopefully that clears some stuff up for you. 1 Quote Link to comment
banzai510(hainz) Posted November 21, 2008 Report Share Posted November 21, 2008 pin 85/86 is the low current path to trip the Relay. Some are polarity sensitive some are not. 87/87a and 30 is the high amp contacks 1 Quote Link to comment
Icehouse Posted November 21, 2008 Author Report Share Posted November 21, 2008 I always ground 85. 1 Quote Link to comment
shinobi x Posted November 21, 2008 Report Share Posted November 21, 2008 So I assume that I would use 87 to power... let say the fuel pump and not use pin 87a right? Then I would just leave 87a blank...right... 1 Quote Link to comment
shinobi x Posted November 25, 2008 Report Share Posted November 25, 2008 Well after everything is said and done I made my own wiring diagram. Improved from the nice one already made with a more clear understanding of the relay. Also it's in PDF format for a nice clear picture. Again thanks for all the help guys. This is going into a 280Z just in case you were wondering...:eek: 1 Quote Link to comment
shinobi x Posted November 25, 2008 Report Share Posted November 25, 2008 ok so the PDF didn't work :blink: but here is the JPG And here is the link if you want it in PDF format: http://www.dannymontt.com/wiring_for_sr20 1 Quote Link to comment
ppeters914 Posted November 26, 2008 Report Share Posted November 26, 2008 WOW! That's clean. What did you create the drawing in? 1 Quote Link to comment
