Ok heres the low down, 91 dx crx, auto to manual/mpfi conversions, ys1 trans, b18b1 block, head stamp for the date says 9\8, also on the head it says pr4-4. On the intake throttle cable bracket it says p75, now weather its a p75 intake we dont know, we don't know where to check for it and its to cold, The ecu is a pr4a10 I beleave not sure, again to cold to dig for the ecu.

Dizzy is unknown cause the stamp was filed off and it was purchased from a junk yard by a friend who clamed it was off a 91 teg, but the old dizzy was stamped td22u IIRC.

This car was not built by us nor do we know who did it cause it changed hands several times. The wiring is hacked togeather and shorts out killing the car and is in the process of being fixed but basicly, we cant find the correct wiring diagrams to try to fix this car. Let alone knowing what the hell to look for to get the car and motor in perfect harmony, ying and yang and that jazz.

Considering what motor, head, intake, ecu I have, what dizzy number and what wiring should I be looking for converting this car from obd0 to obd1.

Or is it just to cobbled togeather to hope for anything? Help would be greatly appreciated.

Well where not sure where the short is, This is possably the worse looking wiring job I have ever seen, We got it fixed for the most part but the underlining problem is where not sure what all belongs to this motor. We are not sure if the head and intake belong to this block. The valve cover resembles the ZC style cover cause that leads us to beleave its not the right head, but the stamps tell us it does.

Hatchet, it runs and drives but we cant find the wire that shorts out and kill sthe car. if we had a diagram then we could get this sorted out but I dont think thats possable at this point, I think we need to start over with a new harness.
