Ok, So I need some help with wiring.
I am swaping a 1981 l28et into a 1976 280z
I recently just found out that the wiring harness and ECU that I have is from an 1982; after checking the serial # on the computer and noticing that the wiring harness did not have a hook up for the dropping resistors. I have been having difficulty understanding the wiring diagrams for both the 1981/2 harness and the 1976 harness. I have been using the Bumble Z ( wiring torutrial as a reference but I am still confused. Most of what I have figured out is quite simple: the injectors, CAS, other sensors, but thats about it.
1. The Coil and Ignitor
This is my original coil. What can I remove from this harness what should I keep?
This is my "new" coil I do not have the part of the harness that plugs into it but I have firgured out a way to make a plug for it I just need to know what goes to what. The pins on the ignitor are shaped like a T (a Black w/ whit wire and a Blue wire run to the ignitor from the coil) I cant figure what I should wire to this But I am pretty sure it has to do with the computers spark control.
2. Fuseable Links
I have both fuseable links right now for the old engine and the "new" In this picture I have them mounted next to each other.
I understand from the Bumble Z tutorial the only wires I need are the green a brown wire on the "new" harness. I am a little uneasy about removing or cutting any of the wires that lead to the existing fusable links. (Do I need this to run my lights or fuel pump?)
3. Ignition Harness
This was pluged into what I belive is the ignition harness of the "new" ECU and the back end of this plug should somehow run to the ignitor/coil. In the bumble z tutorial he had a 6 prong plug, his one has 8.
4. Switched Power
In the tutorial there are a lot of things that need to be run to switched power what should I use? I think I have firgured out that the black w/ white wire that runs to the coil should be switched power but im not really sure.
I will really apreciate some input please dont tell me to search more, maybe at least point me in the right direction. I live in the Seattle area but my car is in lakewood (hour south of seattle). If there are any wiring gurus that can help me I would more than greatfull. Also I am a college student at Seattle University studying photography. i am willing to trade som automotive photography services for help with the wirring.
Side Note: I am really losing morale I already have had one of the turbo engines I was working on stolen that I bought for $1000, wich is a lot of money to a college student.
Thanks for all the help!!!
