So i just picked up a HF from a buddy...
The Crx is in mint condition and just the chassis...

what i dont get is ... are the 91 civic hatch dx CHASSIS harness the same as HF?

i have a d16a6 right now running in my 91 civic hatch dx ..

i had to pull the engine harness off the d15b7 and put it on the d16a6 and convert to MPFI
and now it is running...

now i want to part the engine out and put it on the crx

can i just use the same engine harness and plug and play into the HF???
or do i have to slap the Si Engine harness back on??

 

So are you asking if the Civic engine harness will plug into the CRX dash harness?

 

correct

 

if your car has the HF chassis harness, you need the HF engine harness - the Si engine harness is not the same as the HF
