What harness am i going to use to when chaning in a b18b1 swap into a 91 hf crx? Mine or the ls .

 

if you use the HF harness on the motor,then you will only need the ecuPR4,Dizzy,injectors,& map sensor..
OBD-1 then U need a converstion harness for the ecu ,then a list full of wiring..

 

How will my ls dizzy hook up to the hf harness?

 

if it is obd0 then its good...and plus hf is wired multi port n e way....

 

You will need to replace some stuff on the B1 to run the crx harness..... what year is the motor? Is it obdI or obdII????

 

obd1

 

i think youll just need a non obd distributor or someone to rewire yours to make it work, youll need an obd-0 LS alternator, and you have to rewire the injector clips... I cant think of anything else right off top... Honestly, Id just convert it to OBDI to make it easier

 

you can rig the HF dizzy for temperary intill u get the right 1
this way it will plug in/work ...
