I have a 88 Crx DX and I am wondering if i can use a HF under-dash harness with SI engine harness and SI injector resistor box so that its just plug and play and no wiring for MPFI for my b20 swap? I know I will have to extend some wires on he SI harness for the B20 motor. But can i do this?

yes it will work , u can u hf or si both have fuel injection set up.

 

Yes, if you use the inside harness and the outside. But thats alot of damn work, running everything... just make sure its from a 88-89... or a 90-91... you can't mix them because the wiring is different.

 

I bought a 89 HF under-dash wiring, so your saying i can't use 90-91 si harness only a 88-89 si harness??

 

Some of the wiring is different going to your gauge cluster, etc... less wires were used in 90-91 so I assume there will be some sort of problem with doing that?

 

So you "ASSUME" it will not work. But you said "the wiring is different going to your gauge cluster" are you talking about the DX cluster because i have a SI cluster laying around that i could use if the harness wont hook up to the DX cluster. Would that take care of the problem of the cluster? The hf and si clusters are interchangable with no modication right?

 

88-89 clusters and 90-91 clusters had different wiring.. get a harness to match the specific year from your gauge cluster and it will work.

 

It's not simple plug and play because the plugs where the engine harness meets at the shock towers to the cabin harness is different on DPFI cars then it is on MPFI cars. This leads to using the under dash harness and engine harness both . It can be done but I think it's more of a pain than doing the regular MPFI wiring. If you've already got a MPFI engine harness, just remove the plugs you need and rewire
