OK that was one long sentence... I'll try to give it a shot. It sounds like you are using the cables from the LS1 donor car? For the neg, long one goes to the block (convenient place is on the front lower right corner just above the oil pan. there are 2 threaded bolt holes there). The other I have been running to the fender just above the battery where the factory had a small pigtail secured off the neg cable. Should be an eylet in the fender just for this purpose. For the POS cable, I usually remove one of the 2 secondary cables. The main long one runs directly to the starter. I run the other to a junction block that I like to mount between the battery & the inside of the fender. This is on a first gen F body, not sure if you have the room there, but you can mount the junction block anywhere you see fit. I use the junction block to power the vintage air, electric fans, relays, etc. Scott
