one of my friends has a 94 vx hatch with the d15z1. He got a 94 ls integ and after the swap the wiring is all to hell.... when u turn the key on the fan comes on for the radiator and when you try to straight wire the starter itself it somehow back feeds to all the other power options. Both cars are obd1 is there any wires that need spliced or re wired?? thanks

 

also we kept the wiring harness for the LS on it, should we use the single cam wiring harness?

 

Ok, I'm a little confused here...

So, you have a 94 Civic VX hatchback with a B18B in it? Correct?

 

correct, the motor is also a 94 Ls motor. Both are obd1 and we used the wiring harness and ecu that was in the integra on the hatch. Sorry if i was hard to understand were getting frustrated with this

 

What do you mean by backfeeds to all other power options? What exactly happens when you attempt to crank it?
