Taylor has their catalog on their website now in Adobe PDF format. I found the answer to my plug wire question, view their wire set catalog and look for Pontiac V6. It will give you this page:

It says 1988-1990 V6 VIN 2.8W, 3.1T,V GRAND PRIX, 6000
You can get the cheaper "Hi Energy wire sets" P/N 64630 for $22 at Summit, or you can go straight to the Spiro-Pro wire sets available in red, black, and blue for $39.69 P/N 74x30. Both sets are custom fit, apparently.
Part numbers work like this. On the Spiro Pro sets, the part number is really 74x30 where the X is replaced with 0=Black, 2=Red, 6=Blue. To get them at Summit take any Taylor part number and prefix it with TAY- so for example the P/N from Summit for the custom fit Spiro Pro wire set in Red is TAY-74230
I am ordering them tonight, they worked real well on my GMC Syclone so I am hoping to have the same results on my TGP. The only problem is they are 8mm which may be too big for the factory wire looms.
Let me know how they work. I need to find some good wires for my TGP also.
I had a problem when I built the IROC with the wires fitting the looms, and keeping them from getting close to the headers.
To solve that problem, I enclosed the wires in pairs (V8, 4 pairs, 2 per side) using black spiral flex split wire loom, exiting not too close to the header tubes, I used what is called a NASCAR (that's where I first saw it, but may be used by many other series also) plug loom.
I will be replacing my wires when I get some time to start enhancing, right now I'm still in repair mode. I threw on a set of stock wires to fix a problem, and they don't quite dress in w/ the right length, so I will custom cut and crimp the new ones, and of course since that will be the last time the factory looms stand being messed with, I will dress it in spiral and use the wiretie looms.
A NASCAR loom is a pair of wire ties, the kind that drug cops use for raids, but only a much smaller size, say 3/16ths X 4" long. Form the first into a circle around two wires (or 3 or 4), and use the second to pull the circle into a 8 shape, tightening each a little bit as you go. Eventually, you'll have a slightly snug (not too tight) 8 holding 2 wires in parallel. Like I said, you can use this trick (I've seen many race cars dressed this way) to loom 4 together, then break out each plug separately in a 4-3-2-1 and it makes a neat appearance that true wrenchers will appreciate! Any one can go buy chrome, but to craft parts is true to the old time hot roddin, and I guess I'm showin my age there!
Let's just say, I appreciate riding in a sled once in a while!
You don't happen to have pictures of that do you? Sounds pretty cool.
I will try to get a shot of the loom this weekend, and email. I am going to post pics of the projects on a web site when I get time, later in summer.
