I am not sure why you want the car diagram. there are only a few points where the EFI wiring needs to interact with the car wiring itself.
1. the starter motor is the same as the 18r-c so the wiring is the same.
2. The alternator is as well. just wiring it up the same way.
3. you need a 12 volt feed for the ecu and relays.
4. you need a signal from your coil's -ve for injector pulse.
5.you need a start signal for the cold start injector circuit and a signal for the relays for when the ignition is turned on. You can get these from the wiring that comes out from the key barrel. there is a plug that comes out from the steering column that contains these. there is a main plug for all and then after that there is a smaller one that contains just the ones for starting, just use a test lamp and turn the key to find which one you need.
that is all you need.
