After market cruise control

[Tacoflaco]

Looking to get some help if anybody knows where I can find a cruise control switch I have a part number for a module and the wire harness. But can not seem to find who made the kit. Harness #203-6893

Check with Advance Auto Parts, looks like a dorman part number, if not they could possibly cross ref it.

Back in the 90s I used to install kits from Rostra and Audiovox, not sure how old your truck is but if you k ow the dealer that sold it they will probably know who installed it. other options are call or email Rostra and Audiovox

I did more research, I can't post links but if you look up "The cruise control store" they have an 800 343 1382 they should be able to help
