wiring headache

[1phatcivic28]

every since i did my B16A swap in my 98 Civic Ex i have had nothing but a wiring headache... so i am just gonna start over and get a new wiring harness and ecu... so i need help on what harness and ecu would be the best... right now i have the 00 Si ecu and harness... should i use a 98 EX harness???? and a p72 ecu???? or what would be the best working combo????

ill try to convert it to obd1. use si/ex/cx/ect harness(92-95) and use a p28, cheaper. thats just my toughts, no knock sensor and lots of chips for ecu.

or use ur harness from the car and get a 96-98 vtec ecu.

its up to u

how hard is it to convert to an OBD1??? and how do i go about doing it???? and will i still be able to use my gauge cluster, or do i need ot get a new one?

 

[1phatcivic28]

and........... doesn't the ecy have to match up with the distibutor???? don't they both have to be obd2 or obd1???

No keep your stock harness and just run the p72 ecu from like a 97gsr.. But keep your existing wire harness, thats what im using in my 98 hatch with an ls/vtec. If the motor is obd1, just get an obd2 distributor and obd2 injectors and thats it...

 

[1phatcivic28]

but... i already have a 00 si harness and ecu, but i just bought a p72 ecu today which is obd2... so is it ok that i have the 00 si harness????

 

[tnsxsear]

no its not ok cuz your car is a 98 which is obd2a and your trying to use a harness from a 99 which is obd2b, just use your stock ex harness and the obd2a p72

 

[1phatcivic28]

could i use the harness from a 98 integra gsr???

 

[tnsxsear]

Yeah you can use it also,-paul

do not get obd1 harness, if you want obd1, use stock harness, get obd1-2 jumper and use a chipped p28. you say you have a p72, which is a gsr. you'll have early vtec which will kinda sucks for that motor.
