Hey ppl. I'm doing a h23/95 prelude si to JDM h22 swap and had a few last minute questions about wiring. First, where is the extra a/c fan switch located on the usdm engine that i have to put on the jdm. Second, how do i get an internal coil distributer cap for the h22, i heard that i can use the cap from a 2000 civic si but i'm not sure. Also is there an internal to external and external to internal distibuter wiring guide on this site? Third, are the vtec solenoid and oil presure switch the only two wires i need to run to the new ecu or is there another, and how can i tell if my car is already wired for vtec as i hear some are? TIA for your replies.

 

wiring is a very simple job. 2 wires to the ecu and one grounded. so the vtec solenoid and vtec sensor are the only 2 wires actually going back into the car. you can ground somewhere in the engine bay.

as for the distributor, why not just use your old h23 one? it's what i did and had no problems finding caps and rotors.

 

I was thinkin about using the old one but i heard it was a pain to convert from internal to external

 

no man u can use the old dizzy, ur thinkig of the ignition coil and you wnt to use the external one (should hav come with ur jdm engine). and look to see if your car was wired for vtec already. mine was dn it was a 93 si (h23a1)
