obd1 to obd2 dizzy wiring
I'm replacing my B18A for a B18B w/ head.
From what I gather through searching I can simply repin the B18B dizzy wires to the B18A plugs. Correct? Question, however, the three white wires on the original OBDI plug, where do they connect to? From what I understand all colors will match up with the original harness leads except these three white ones. Can anyone confirm matching of these wires?
On a slight tangent, if I retain the B18A intake manifold w/ injectors and the exhaust manifold w/ O2 sensor everything else is straightforward minus the dizzy, right?

You will be able to use your old dizzy on the new head. I read your sig and you have a 90teg so your obd-0 so a obd1 or 2 dizzy wont work unless you convert to obd1

Re: obd1 to obd2 dizzy wiring (Magick211)
Thank YOUUUU....
Also, while transferring everything other to the new engine I noticed a difference in sensor location. Oil temp sensor on the old B18A doesn't seem to exist on the B18B.??? And, the oil pressure sensor will require swapping out a bung??? Can anyone confirm this?
BTW I actually live in Grandview now, 14miles south of Cleburne. I guess I should change that.
