I am a owner of what I thought was a great 81' Jimmy. I have a couple of questions and was glad I found this site in 4 wheel and Off Road!! My Jimmy's wiring harness is a mess to say the least! I have no running lights but when I step on the brake, the running lights come on? Go figure. But to my problem. My truck on hard left or right turns has hard roll over, everything is tight though. The Dude I bought it from put street tires on it 275/60. Are the tires part of the problem? Also I neeed a good manual, I have a chiltons but the wiring diagram leaves something to be desired. Any suggestions? I thank all of you guys in advance, from surfing the site it seems like ther are some great guys out there helping each other out! Thanks in advance!
