I am putting a 1992 LS into my 1991 CRX DX.
I dont have a dizzy or harness. Which should I use?
(i do have the PR-4 ECU)
P.S The CRX had a D15 w/ points
TIA

 

Need to first covert the car to 4-injector wiring, and then use the CRX wiring harness on the Integra motor. Use 90-91 Integra distributor, injectors, ECU, and misc parts for your swap.

 

I get the points to injector conversion...
but i use the old harness with the new motor?
and i need to junk the obd1 ecu and get an obd0 out of a 90-91 along w/ the dizzy, and injectors? anything else?
p.s. thanks a bunch

 

I have a similar setup in my 91 CRX DX: 1996 B18B1 with 92 YS1 GSR tranny. I used the 90-91 OBD0 PR4 ECU, distributor and injectors. In addition to that you'll need to get some OBD0 injector clips and a resistor box. Reuse your DX harness and rewire it from DPFI to MPFI, rewire the coolant temp switch and extend a few sensor plugs and you'll be in good shape.

 

thanks guys, seriously a big help.
anyone have obd0 PR4 or dizzy or restitor box?

could you elaborate on that please?

 

On the older OBD0 motors the coolant temp switch is on the back of the block to the left above the oil filter as a big rubber plug with 2 female connectors. On the 92 LS it's either mounted on the in the same location on the back of the block or on the thermostat housing but as a regular 2 prong plastic sensor. You will need to rewire the plug on your DX harness with a regular 2 prong sensor plug and extend it if necessary.
Check your B18A1 block to confirm this though. As for my 96 B18B1, I had to rewire it and extend the wires to the thermostat housing. I have a 90 B18A1 in my garage and it is still located above the oil filter but as a 2 prong regular sensor as I mentioned.
