Alright so i finished my cousin's CRX OBD1 D15b8 swap a while ago, just haven't had time to get all the little things done.

Alright, so i used his HF harness, OBD-0 injectors and all that good stuff. So here's the problems:

Since i used his HF harness, i have a left over connection, and i don't know what i'm supposed to re-wire it to.... here's the pic.


This is where these wires used to plug in on the OBD0 block just for reference.


Also, his OBD0 engine didn't have a thermo switch in the same location as the OBD1 engine, so i put a thermo switch in, but there's no harness connection for it...what do i do?

 

LOL!

yeah - that two pronged green sensor is just the radiator fan switch!

you just run a pair of wires from the engine harness plugs (in the top pic) to the new thermoswitch location and it will sort it

too easy!

 

try connecting those two plugs together with the ignition on and see if the rad. fan comes on,

you might just be able to plug the plugs onto the sensor and see if it works when it gets hot?

you might not need to extend the wires at all!
