KA24DE to Ka24e Almost done, Need some little opinions/help please - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

As strange as the swap sounds, its almost done.
Reason I say ka24de to ka24e is because I picked up a shell that had the ka24de body harness/electrical harness in it (harness that connects to gauge cluster/rest of the interior) and I have a ka24e motor that I'm putting in it. I believe I have all bolted up and now I'm having some questions/problems when it comes to connecting the harness. I have the harness connected to a ka24e ecu, but where the ka24e harness connects to the interior electrical, the brown connector and the white cable don't match up, I seen reviews/diy even youtube videos step by step on how to go from sohc to dohc, but how does it work when its the opposite? I know the 4 wires that are literally in the same location but what about the rest of the wires that are on the dohc harness, are there grounds that need to be hooked up or other vital wires that need to be connected for everything to work?
Another quick question is what fuse or wire has consistant power to it? I just wired up everything up to the connetion on the interior harness and want to make sure i'm getting power so at least I know i somewhat did some connections properly. I'm getting very pestimistic about the project because its been taking too long and I'm no 5 star mechanic. I just want to make sure something is getting juice so I know something is at least right
If i put my foot on the brake pedal shouldn't my rear brake lights light up even with the key not in the ignition? Idk. This is a lot to read and I really do appreciate anyone that reads this through and understands and has some insight for me. Any info or ideas would be greatly appreciated, thank you.

Just match the wire colors on the dash connector cut and splice or move them in the connector. I did the opposite swap and I don't remember having to make alot of changes to wiring. Make sure that the connector in the engine bay near the battery box is plugged up I think it has like 6 holes in it.

i was thinking it was the same but wasnt sure, and on top of that. would you happen to know what fuse or wire has consistant power so i can know that power is at least distributing through the wiring harness?
thank you for your time in responding.

fcknslo · 12-17-2010, 07:52 PM

and I'm assuming because it not wired up nothing on the gauge cluster will light up?

yeah without that dash connector alot of stuff wont work. check the fuses out in the engine bay near the battery for power. i dont remember off the top off my head which ones.

Oh quick question. Why are you going sohc instead of dohc. Just wondering ;-), gl.

Thank you for your help and to be honest, I had the sohc for a long time, has about 20k on it and just seems perfect to maintain, they are super easy to work on and with such low original miles on it, its perect for a small turbo build later on, just trying to be unique and enjoy the fact that it will be different.
thanks again guys!
