I KNEW (past tense of know) of one LOCAL person who purchased a Pantera and was intending to prepare it for "road racing".
He inquired here about a wire harness, then turned and dismissed all responses as being unknowledgeable. Informed all that the Francis unit was what to use.
About a month later he sold the car. I presume that it was somehow, undoable/unworkable, etc? Don't know.
Personally I would say, there isn't anything wrong with the original harness. In fact, it is the highest quality unit available with marine quality plated wiring.
The mention of the "bad" Italian electronics in the car is just another example of unknowledgeable people spreading untruths or maybe alternate facts?
They are high tech for the era, were limited to European market thinking and nationalistic sourcing. They are very updatable reasonably now.
They are undeniably different thinking from what would be typical in a North American built vehicle of the era and therein creates much of the criticism.
The connectors used are available separately now also if they need to be replaced.
Wilkinson contracted with Pantera-Electronics to build some. How many? I don't know.
Does Pantera-electronics have any left from the build for Wilkinson? I don't know.
Does Wilkinson have any left to sell? I don't know. Ask him.
www.panterasbywilkinson.com/What do/did the new harness cost? Ball park, $3,000.
I think from what I saw of the harness, just in bulk scrap for it's copper content, it is worth several hundred dollars?
The comment from Haas on the original harness was 1) he identified three variations of the harness 2) there were a couple of mistakes in them that needed to be corrected. If you want specifics, ask Jon.
