does any one have a write up on how to convert every thing to obd1.i know its just a 4 wire o2 and a conversion harness plus a obd1 ecu and distributer.but i would like a walk through or something for reasurance.thanks

 

when you buy the conversion harness, it should tell you information on how to use it and convert propertly,like blown90hatch makes harnesses with step by step instruction on converting.

 

oh i didnt know they came with instructions.
ok and one last question about the 4 wire o2 sensors, 2 of the wires zre for a 12 volt source one for the sensore and th eother is a ground? does any one have any tips on how to pass a ref test?

 

also tells you how to do it on in the instructions , all 4 wires should all go into the ecu if you use the harness from blown90hatch.(i use this harness)

Run two more wires for the o2 sensor, install the new parts, read the instructions that came with the conversaion harness. Takes about an hour to get it to run and 2 more hours to make it look good.

I used a blown90hatch harness

 

ok thanks,for the help.
