when i ordered this part i was very sceptical because of the price but when the actual harness arrived at my door and i opened the box, i was very happy to see a complete custom harness. usually when you order a part you cant see first you kind of wonder how it will look but this harness looks great and all of the plugs are high quality. i have already told several people about this harness and plan on ordering another one for a project i am building for my brother in law.

Does this harness come with the 700R4 wiring to control the TCC lock up?
Asked on 8/20/2011 12:47:58 PM by Ray from Minneapolis, MN
The Speedway kits and the Painless kits do not come with the wiring, vacuum module, or senders for the various automatic transmissions such as the 700R. Speedway and Painless wiring harnesses are generic for hot rod applications or transplants into different vehicles. We do offer the lock up kit from Painless under number 91064038 if this would be of help.
