I am using an hf engine harness with an si body harness..

are they different? will it work.. because it wont start..

 

I would think yes, but I do not know for sure. I would test the wires at each end. here is a coulpe for you to test, the four injector wires. test at the injector plug and the correct ecu pin, if the hf/si harness match up then the wires should be good going through the plug. it sounds like you have some wiring troubles. good luck

 

i dno.. I'm getting fuel.. but no spark.

 

see if can use somebody's dis. and see if yours is bad? when mine went out it would do everthing but start.

 

no luck on that one.. i dont know anyone else around here with a honda.... everyone has the drifting fever. got friends with AE86's out the ****.

I just dont see why the dizzy would have problems moving from one car to another..

 

at least check all the wires for it.

 

I cant say for sure, but I cant imagine that the 1.5, and the 1.6 have the same harnesses. I know that while I was looking for an Si underdash harness I got an HF underdash harness by accident and it didnt work.

Go here (Si harness)

and here (HF harness)

And you'll notice that only 2 of the 5 harnesses listed in the car are the same part #. They dont have pics though.

Odds are it wont work, unless you make it like an Si engine harness, or use an Si engine harness.

 

Pull the 2 wire plug on the dizzy. Make sure you have 12V from blk/yel to earth and 12V from blu to earth. Check the coil and igniter.

 

ya, different part numbers. the engine harness came from an HF.. dropped the engine into an SI.. and left the underdash harnesses. look like im going to have to trade the dashes out too.

 

and I have checked the wires on the dizzy. I had 12 volts

 

Different harnesses, si, dx, hf all different pinouts. Also... fyi years are hardly interchange either(with some exceptions).

ok, so that is definitely a problem? the hf engine harness with the si inside harness? the plugs fit perfectly together.. if i swap out the dash and all that wiring.. everything should be gravy?

Yup, or put the hf one back in, lol

 

lets seee what happens.

 

anyone else have any suggestions.. an 88 si engine harness in the 90 si.. OR grab the underdash harness from the 90 HF that the engine came out of.. and throw that in the 90 si?

 

Underdash harnesses are a beyotch. You have to pretty much remove everything down to bare metal to get at it. If you can just swap out an engine harness I'd do that first.

 

the car is already gutted, just took the dash out.. I was told that the 88 si engine harness wouldnt work with a 90 si underdash harness..

 

just to be sure.

so 90 hf engine harness wont work with a 90 si underdash harness?

 

fixed.

the guys that made the harness had some wires in different places.

nothing a voltmeter and aligator clips cant fix.
