My brother is planning on swappin' a b16a2 into his 90 integra. So far i've found that the dizzy, injectors w/resistor box, ecu gotta be obd0. The only thing im not getting... is the wiring harness. Is a conversion harness the way to go? What other way is there? Any help would be appreciated.

 

hes just going to wire vtec into his current harness..

along w/ an obd0 dizzy and ecu...dont know about the injectors...

look in the engine swap guide here..

he'll need his factory engine harness

he'll have to get low impedence (obd0) injectors... just use his stock LS injectors since they're free and probably still work. they also have the same flow rate.

he'll also need an obd0 dist. and you might need to swap a few head and block sensors over from the LS, i forget exactly what. you'll notice that there are a few more sensors on the b16a2. dont worry about them, they're obd2 stuff.

after that he'll need either an obd0 vtec ecu (like a pw0 or pr3) or an obd0-obd1 ecu conversion harness with an obd1 vtec ecu.

then he'll need to run the wires for vtec sol, oil pres safty switch, knock sensor to the ecu outside the harness or inside the harness... whatevers easiest.

 

Injectors have to be obd o if use obd o ecu or you can cut inj. wires and use obd 1 clips if you have obd1 inj. whatever you want tyo do doesnt matter all there is is vtec wires

 

you have to use the resistor box if you use obd0 injectors.

do not use the resistor box if you use obd1 (or later) injectors.

get correct pigtails accordingly.
