So this is for my reference but figured i would post it here.
Im trying to mate a stripped down GVR4 harness to a 89mirageman Plug and play harness for a 93-96 4dr mirage evoclone.
I have had a hell of a time getting the conversion right so im posting pictures for me and others to use for reference at a later date.
So these are the plugs in question there suppose to fit the dash harness of the mirage which they do perfect. But they dont fit a GVR4 enigine harness i found the difference in 1g to GVR4 engine harnesses its these plugs i believe.
So first is the white plugs im going to repin the second set of pictures is from a 1g harness that obiviously isnt the same plugs that are suppose to mate to the plug'n play..

So here go's






So if you compare the plug pictures to a 1g you can see there totally different so what are the plug on the plug'n play
Maybe from a 90 dsm?

This would be #1 on the p'n p harness but plugs are different.

Once again different plug to what i need this would be #2 on plug in play

And This would be #3 close but pin/wiring isnt in the plug 'n play

Those 3 plugs on the adapter will plug into any 1g dsm 91-94 manual engine harness. Are the bottom pics of the GVR4 harness?

So this is my take on it all for gvr4 i traced each wire one by one to see where they went. So this is my pin out
For the GVR4 white harness plugs there are alot of pins missing now after my wiring stripe down!!
Hand drawn and all if some one wants to type it all up i would be for it. But as of now im to tired.

More tomorrow when i get some time to work on my wiring so everyone can read it not just my chicken scratch.

For now these are the GVR4 white plugs alot different then a 1g harness

Oh OK, they are using a 90 dsm engine harness in those pics. Two of the plugs are slightly smaller on the 90's.

So here it is my baby,
All the wires were traced back to the ecu and i used the vfaq pin out to decifer what went where.
The spots where it is labeled N/A this is apart of the stripped down part of the harness alot of it would be a/c controls and dumb worthless stuff no one really needs i think hahahah.

If you guys have any input please do help.

SO ZOOM IN AND ENJOY! HI RES JUST TINY AT FIRST
