i did a swap on my 94 vx eg hb i use the ob2 harness that came with my motor on the right side of my car 3 wire sucket fits from my vx wire sucket and the 4th one are different so i just leave it unplug the was running fine but when i use the ob2 gsr ecu the wont run good rpm is too slow when im driving,i install a gsr distributor with a b16 coil would that cause the prolem or the secondary butterfly?

 

I recomend you get the obd1 harness, everything will plug up except the distributor but you can change the plug on it from your old dizzy. Then you can just use the obd1 gsr brain and it will run like stock.

 

i was told by one of the shop over here to use my ob2 harness
