burb trailer harness?

[capev86]

wanting input on adding a 4 way trailer harness to my truck (i will be adding a 4 to 7 with trailer brakes in the future). i could just splice wherever (behind the lights, underneath, etc). anyone looked into making a plug in adapter like they have for the pickups. i bought one of those and then found out it won't work (does it work on blazers?). any ideas on how to do a clean install that will be dependable. i may be wiring up the lights this weekend so i can use the burb to move a pickup a friend just bought. my dad has a tow dolly, but his '87 burb has a shot brake line....still.
