OK. ive done a fair share of research for the past week on this i thought i had it right but now i'm questioning myself. ok this car has already had the mpfi conversion im guessing, cuz it had a d16a6 that ran perfect in it before pulled. So i need help to wire the vtec solenoid and 4 wire o2 sensor to the DX harness(which pins?) This swap was in a crx si that my freind still has and hes reusing the obd0-obd1 conversion harness to a p28 that was originally in ths Si. Car isnt starting but we had it started before when we moved around the Dizzy and was fine in the DX using everything we had setup now??? SO BASICALLY IT'S A:

JDM B16A into a crx DX using the d16a6 sub-harness and the DX chassis wiring harness to a obd0-obd1 conversion harness to a Tuned P28. need it to start up again and 4wireo2 & vtec solenoid wired correctly. Its also throwing a check engine light dont know how to check for what it is!?

*Much help would be appreciated on this and sorry if i overlooked this topic..

 

so you have a DX with a Si engine wiring harness??

 

DX

 

you said you have a Si sub-harness and a DX chassi harness

which one of these do you have inside the engine bay??

 

alright it seems both are DX.

 

bump for some info

 

do you have an obd0 dizzy or obd-1 dizzy? you need an obd-1 dizzy if you have the obd0 one

 

im not sure, anyway to check?

 

he was saying you need the odb1 if you arent using the resistor box. you can do odb0 but you need to wire the resistor box in there

 

now to it be obd1..you have to use an obd1 dizzy and a 4 wire o2 sensor?..also what about an ecu?..

and what about the dizzy plug? do you have to wire the obd0 one to the obd1 dizzy?

it should have grey plugs if it is obd-1

things that need to be obd1-ecu,dizzy, plus 4 wire o2
ecu needs a p30 map(could be more maps for b16 but not sure of the names)

you can hardwire the dizzy to the obd0 plugs or buy a dizzy harness for about 20-30 bucks
