I just installed a JDM H22a in place of a bad h23a, in a 94 Prelude Si. The JDM motor was a manual, and the Prelude is an automatic. I'm going to wire it up this weekend. Most of the plugs are the same but:
1. The distributor on the h23 has an external coil and the plug on the wiring harness to match it. The H22 has an internal coil. Do I just use the whole distributor off of the h23?
2. The fuel line on the h22 is on the right side of the engine, the stock line is too short. Do I buy a longer line or try to switch the fittings to feed the rail through the left hole?
3. I know that I need the p13-auto ECU, but I need to know which wires to run for the VTEC option. I heard it's 3 wires but don't know where to find a pinout on the "net".
Any answers fron somebody that has done this before? One company was going to charge me $250 plus shipping to convert my stock wiring harness! What a rip-off that would have been.
I 'll probably have more questions and some answers after I get it running. I finally got it all bolted in last night.
