I'm leaning heavily towards using the Speedway 20 Circuit GM Wiring Harness Part # 91064027 for around $165 plus shipping.
Has anyone used a Speedway harness?
I bought one of these
My first impression was it was a nice kit---still may be.
I have wired a few different cars so I tend to really examine a harness
to get a bit familiar with it. (Using different kits)
Have found errors in a couple of the kits and returned one due to mismarking
Now--the 20 circuit speedway kit
Found an error that could be a bit troublesome to someone wanting to use that particular circuit.
Since that kit is so inexpensive, I thought I would send a note to who I "Thought" may have produced the kit.
The reply I got was pretty much that that kit is a cheapo chinese copy
of a major supplier over here.
The box the kit comes in--------(except for the printing)
All of the instruction sheets-----(except for name in lower corners)
And virtually everything else about the kit
is a COPY of a first run kit of our USA supplier.
Right down to the wire numbers, spelling, drawings and yes---even the afore mentioned error in the documentation.
I bought the kit from a suggestion on one of the forums I visit.
Had I known it was a "copy" I would not have purchased it.
Have made several modifications to it as it is going into a Falcon Based Ranchero.
So---use this info as you see fit.
