#1052 of 1057 tires and rims by blackchevy1 May 10, 2002 (10:03 am)
I just purchased some stock alloy tire with stock Bridgestone tires. I noticed my stock chrome rims and stock Firestone Steelex were different. My truck is a 2001 and his was a 2002. Also I pull a 26' travel trailer 2 to 3 times a year. I read somewhere that you shouldn't use alloys or the will crack when towing, anyone know if this is true. Why would GM offer them if they cracked while towing? Wouldn't most people buy a 3/4 ton over a 1/2 ton because they need it for towing? Anyone hear about anyones stock alloy rims cracking after towing less than maximun towing capacity of the truck? Thanks I am a little leary about putting these alloy rims on the truck.
#1053 of 1057 Kelsey brake controller help by rmartin3 May 10, 2002 (2:03 pm)
Hello, I just bought a chevy 2500HD long bed, 8.1L, crew cab. I lost the directions to my Kelsey brake controller. It has 4 thick wires...red, white, blue, and black. Would anyone know where to connect these wires to the included brake wiring harness, which has a thick red and blue, and thin light blue, black, and brown wires. I am a novice at this kind of thing. Thanks for any help

No, the alloy rims will not crack from towing. The dynamic strength of the alloy rim exceeds that of steel. The downside of alloys is they can be cracked with a direct impact, ie curb. Wiring up a brake controller: All brake controllers use the same color code, but pay attention as it is not the typical color code one would normally see. The colors are like this: Big Blue: Output to the electric brakes. Big Black: +12V from the truck (Input to controller. Red: Stoplight switch to activate controller. White: Vehicle ground, needs to be a really good connection to the chassis. Brown wire is for illumination if your controller has it. Most do not, so just tape off the wire. If you are wiring this up to a late model GM you are in luck as the GM supplied harness is labled for you. If the harness is not in the truck, they can be purchased at any good RV shop or hitch company. Have fun. Jim
