Hey guys, quick question. I am doing a 93 LS swap into an 88 crx si. Does the LS motor have two coolant temp sensors? One under the distrubutor and one on where the thermostat is? My harness only has one plug so do I not use one of the sensors?
Thanks

 

What harness are you using?

 

I am using the 88 si harness.

 

If youre staying OBD0 than just pick one, youre ECU will only look for one.
your 93 Ls is OBD1 so it has a 4 wire O2 sensor BTW. You'll have to swap your stock O2 in place to be able to run your ECU.

FYI, I did a OBD1 conversion on my 91 hatch and I only had one plug also so i just picked one and never had any issues.

 

ayy i have the a 92 b18a1 on a 1991 si and im with the obdo harness and ecu. ayy by the way do you how to run vacuum lines
