Is this a good spot for my ground? Does it have to be directly on the car chassis or is this good enough?
Hrere we go, I made the ground from the battery alot shorter and bolted it to the car chassis, I scraped away the paint of the chassis its just not very visible. Tell me what ya think.
Looks good. The frame would be a better ground though. The only thing I would suggest to you is to "loom" the wires a little better.
not many cars have frames anymore...most cars are unibody construction. Nowadays trucks and some suvs are true body one frame chassis
/agree with Azn and DMP if any one but you gets under the hood you dont want them making any mistakes for all saftey reasons! but other than that GOOD JOB!
