yeah so I have a 91 DX hatch shell, and a crx si motor to go in soon.

so instead of doing the mpfi conversion I bought the full cabin harness from a crx si for it, my question is:

Do I have to change over the floor harness (one that goes under the seats and to the tail lights) also? Or can I use my DX floor harness with an SI dash harness?

I've gotten most of it together except for a few plugs where the floor and dash harness meet, and I can seem to find where they go. Any help is greatly appreciated.

these are the ones I'm having trouble figuring out:

the large one comes from the floor harness... can't find where it goes on the dash harness:


these two I can't find either:


and I have no idea wtf these are for, there was nothing like it on my DX dash harness:


help me out please

I took my 88 si full body harness out and it seeems to be one piece other than the motor harness. Why dont u just do a mpfi wiring, its only like adding 4 more wires instead of this entire mess u have to go through.

 

looks like speakers wires for the rear. and the other wire with the bigger plug might go to the slider behind the door (right around the paint code sticker area).
not real sure about any of it though.

because quite a few of my dash wires were hacked up. /this way I just plug in the si motor. Plus I'm already way past the point of no return.

cool get a helms, it shows all the plugs. ALso dont forget the si has a sunroof, your going to have an extra plug for relay (on the fuse block), the switch and the motor its self.

 

The first picture, Your dash harness plugs in to it.
The second picture, I think the six pin plug goes to your blinker mechanism.(blinker and wiper controls)

 

nah expletive it I'm just gonna put the back half of the harness in too... should be way easier than the dash portion anyway, at least then It'll all plug together correctoy.


So I've figured that long harness in the last pic goes to the sunroof in an SI car...
