Thank you. I have those main 2. The one thats giving me trouble goes from the ground terminal towards the block and down, disapears under mid engine or so looks like it goes towards the front and down into the abis. Need to know how long it needs to be.. Because at almost 60 years old, i dont want to have to get understand the truck more than once and i want to have the wire preped and ready to install. Ty Thank you again. I may just make it long and finished only on one end, can finish the other topside once identified.

Ok, since you have a tahoe about the same age. How long is the ground wire from battery to block. Thank you in advance.

Please list ground wire connection points. In the 2003 denali. I have found the one in the front grill. Ty

When the issue first began, i would have a ticking sound in the dash, the lights would come on, but not start. No crank. I was stumped. I bought a New battery and checked the fuses and relays. Finnally, figured out it was a ground wire...now the problem. I dont know where it hooks to the block. Please know that due to financial limitations i must do this myself (i am almost 60 years old) and dont want to have to crawL under the truck more than once. Thank you in advance for your time and knowledge. I appreciate..my dad was a mechanic and i know how hard you work. Any info would be great

Check your ground wires. If damaged, they can play havock with your systems and make many codes display.
