can i use the stock ls wireharness w/out moddifiying to fit in my car? if not what wire harness would i have to use, i want to stay obd1, so do i get a obd1 pr4 or a obd1 p75 ecu?

 

if you have the 97 ls harness and dist you can use it. if not you can use the ex one and either do a plug change if you have the ls OBD2 dist or get a OBD1 ls dist. also as for ecu's you can use a 92-93 PR4 or a 94-95 p75.

 

o thanks alot, your info helped greatly
