Are there going to be any difficulties when a H22a1 manual into a prelude which original had a F22 automatic. The h22 vehicle is available for parts donations. Will all wiring harnesses have to be used when doing the swap or can the original wires in the f22(behind dash) be used? What exactly are the red plugs located in the dash around the air bag wires? Any info will be helpful...need answers ASAP

 

first of all, SEARCH will help u a lot, because this has been asked many times, and if you are doing the whole engine swap, yes you will need everything, except a couple of wires, which may be reusable, i don't know much more because i already have a h22a4 so, i don't want to speculate on what i don't know...

u will need to add pedals, tranny cable and modify your whole interior where your autoshifter was/is.

good luck, and fun times with real vtec, i tell ya!!
