Does anyone have info or a "how-to" on wiring a '99 Frontier KA24DE into a carbed Z24 720?  I know how to make the engine fit but I don't know a lot about getting the fi ignition ecu wiring grafted into the 720. I PM'd the member with the "wire a KA into anything" box and he doesn't know about wiring a D22 motor into a 720. Anybody?

Can/Am box should do the trick. It's made by icehouse, an admin on this forum.

And for how to actually wire it... look at this thread:

Have you pulled the harness from the frontier? As I understand it, it is part of the complete truck harness?

Whenever I think that I'm out of my mind for putting this much time and money into an old Datsun, all I have to do is look some of your threads to know that I'm not nearly as whack as you are.

You're going to skin a few knuckles, stand up too fast and bump your head, hunt around the floor for the nuts and bolts you dropped, invent a few new cuss words and when you're finished you'll say "That wasn't so hard after all!"

My understanding from Icehouse is that the "wire a KA into anything" doesn't apply to a Frontier KA24DE. I picked up a wrecked '99 Frontier thinking its KA24DE should shoehorn into my 720 with the right m/mounts, right brackets, adding a Can/Am box, etc.  I guessing I was wrong.  Now I'm trying to decide whether to scrap the project, sell the frontier and learn to be happy with my poor Weber/Z24 or search for some other solution.  I don't want to stuff just anything into my nice little 720.  I am looking for an engine "upgrade" but am not trying to turn it into a rat-rod if you know what I mean. Back in the huddle...

If you have a wiring diagram it shouldn't be too difficult to figure out what you will need. It just isn't going to be an easy thing as you have to physically go through the wiring harness. 

 

You might be able to find a 240sx intake, harness and ECU to use on the frontier motor to simplify the swap.  This would give you a nice easy harness and still keep the frontier rear sump. 

 

I have a single cam set up this way, Icehouse is the one that put it all together, so he wouldn't have to mess with the truck harness.

There isn't much info on the frontier harness. The is the best block for the swap, shouldn't have a crank girdle and will make oilpan fitment easier. Now the simple answer is with a donor vehicle you already have everything you need. How to remove the harness is the issue. You won't need a bucket of cash, just a bucket of time. I did a single cam swap like redeye and you quickly forget the heartache of the swap when you turn the key and mash the go pedal. Also I built a run stand and made sure it started and ran before swapping. The harness scared me the most but it really wasn't too bad if you just take it one wire at a time.Beer didn't help so I had to wait for later for that. Good luck and document it since there isn't a sample of your swap floating out there.

I have a shop in South Carolina do my Toyota wiring harnesses. A complete plug and play harness from them is only about $600. They go by two names - http://www.phoenix-tuning.com/and http://www.tweakdper...com/index2.html

 

I'm pretty sure they do anything.

On this same note, Wiring Specialties offers a stand alone harness for the KA

Wiring Specialties says "sorry but we do not support anything for your project."  I can't possibly see spending $600+ on a Tweak'd Performance loom for only a 40 hp increase thru a junkyard motor.  I also don't have the time/information/equipment to devote to OEM harness surgery. Since my 720 is one of my DDs, I think it's most logical to shelf this Frontier engine swap project, do some better research and look for something a little more user friendly. Maybe a D21 KA24e or a VG30. Maybe not. Thanks to all.

It's so easy to do at home. There's only a handful of wires that you need to get it to run. It's too bad that such a simple problem is causing you to dump the whole project.

 

And "only 40 hp"...? That's a 40% increase over what you have.

i swapped an engine out of a 1994 nissan truck after i did a complete rebuild.Used the motormounts from J2eDeYe.Made a carburator adapter plate after plugging the fuel injector holes.Used a matchbox dizzy out of a 1979 620.I did this to my 720,best move i could have made.Noticiable improvement.Using a weber 32/36.All i can say is fun,fun,fun especially since i have 4:11 gears in the rear!!
