I've Googled it & found some info BUT not what I need. I am looking for info or diagram/s to hook up an electric brake dash unit for my travel trailer. 1999 Chev C1500 Suburban...which is apparently the same as '98 and a few years prior. The 2000 Suburban changed as did the 1999 and up model truck? Apparently they held over the 1999 Suburban to the '98 specs. Confused yet? I am.

My Sub is a conversion model but the electrical is not affected...at least down at the fuse box. It came with a factory tow package and I figured it should have a plug already factory wired for electric brake controller but it doesn't. I know there's a bunch of these trucks still in use and somebody has to know the right way to do this. I'd prefer just buying the proper plug and match to a Tekonsha Prodigy unit but even the websites for Tekonsha & others are confusing when looking for a 1999 Suburban...seems they think the 1999 model Sub went the way of the 1999 truck changes while that apparently is not the case. Mine is similar to the '98 and earlier trucks.
