switch2zcar.com down, need z31 wire diagrams for l28et


Recommended Posts

Hi guys, I was wondering if there was a comprehensive and successful writeup on how to rewire an l28et oem harness to work with a 16-bit z31 ecu from 1989. I tried searching for some time now, but I found a dead link to switch2zcar.com and I need the info on there to double check my work.

 

I have a 1971 240z with an l28et at my shop. and the harness has been rampaged by a few of the previous owners and "mechanics".

 

My l28et swap is running perfect on my personal car since i wired it full stand alone with fuse block and relay system. But this other car is driving me nuts. I already have done a full pinout test from the ecu harness to the engine components, fixed a few dozen things....

 

I am getting spark, but no injector pulse (have battery voltage, but ecu is not grounding them. I installed new drop resistors for the oem l28et injectors, rewired and soldered most of the system, found 25 different problems and fixed them. This is where I am stumped for now, need a refresh. Any help would be great. thanks.
