S13 SR to S14 chassis WIRING HELP PLEASE!

[gotta240]

Anyone know of a current write up on wiring a s13sr20det into a s14 chassis?


Or answer the following.....

1. Where/how does the wiring harness that goes from the ecu to the motor get connected to a power source? I have my lower harness all connected to the battery/tranny/starter/alternator etc. I have the engine harness all connected from the ECU to the motor. THE TWO DO NOT CONNECT but I'm assuming they should.

The car is cranking over, but no spark. I'm assuming this is because my engine harness needs to connect to the power (lower) harness at some point....no?

Iv slep since i did mine.. but from what i remember, the sr harness (a few wires,look at current write ups) hooks into the F3 (ka plug) power wires, and i believe the relay mounted close to the ecu.. This is how power is supplied.

The lower harness does not connect to the upper harness via Ka plug anymore, (which you will still have mounted close to the fire wall/fuel filter area) when you hook the harness up according to the write-ups it will bypass the old plug supplying needed power to everything.. Hope this helps some! ha
