I purchased a JDM H22a from Hmotorsonline.com and am in the process of getting it into my Automatic Prelude.

First off I noticed that a lot of the wires had been cut on the H22a and I heard that was because they don't reach to where they need to since Japanese motors are designed for right side steering.

What would be the best way to run the wires? How do I extend them? Should I re-route the harness?

Also, I noticed the canister is missing on the H22a and mine is cracked on my H23 so where could I purchase a new one?

What all is involved with swapping these engines basically? I would like to make sure I don't miss anything. I already have the tranny bolted onto the engine. I will be moving my AC from the H23 to the H22a as well. The main things are wiring the Vtec and other wires (extending them), and getting a new canister.

On that note, does anyone have a link to a diagram for wiring Vtech?

Thanks in advance, your help is GREATLY appreciated!

i got the same q's. somebody help.

 

Swap the harness from the h23a onto the h22a, and use the spare connectors from the left over h22a harness to wire any sensors the h23a harness does not have such as the vtec solenoid. You really need a HELMS manual for the wiring (or do a search for the ecu pin layout), and other than that it should just drop in.

two basic concerns 1) swapping the harness, intergrating the VTEC Solenoid 2)you may need to use your H23 distributor.

 

Ok so now I have the engine in, wiring is done and new distributor is being used; however, I have a quick question, the flange off of the exhaust manifold from my H23 doesn't fit the new JDM H22a that I purchased. Is this normal? Do I need to purchase a new flange now? Thanks!
