Hello, I am in the midst of doing a b20vtec swap into my 1991 CRX DX and i need to know what kind of wiring situation. Will it be the normal dpfi to mpfi conversion or is it a matter of buying a jumper harness?

Sorry for the stupidity, Thank you for the answers!

 

you will need to convert to mpfi and also to obd1. these are 2 seperate things so do the mpfi first and then get the jumper,etc that you need for the obd1 conversion.

 

okay so ill convert it to mpfi, remove the engine, the whatever i need to convert it to OBD1? Im thinking its just the jumper harness right?

 

reassurance would be lovely

 

you need the jumper harness yes, but then you also need to run the subharness wires/connectors into the engine bay and hook them up for vtec, 4 wire o2, etc. then you also need to run an obd1 distributor. you can keep peak/hold injectors if you retain the resistor box, otherwise delete the box and run saturated injectors.

 

might as well tuck it while your at it

 

i may tuck it i may not, but if i dont tuck it ill make for damn sure i dont have it lookin all ghetto with wires hanging every where! thanks for the help!
