just curious because the battery on my car was relocated. is there two ground wires going to the battery? just notice that mine only have one going to the chassy. usually most of my car have one going chassy and one going to the engine block.

 

i only have 1... however i would recommend putting on a second one if you relocated your battery to the trunk.

 

put at least one more... I would run a ground from the battery up and ground it directly to the motor as well. you can never have too much grounds and things like a bad ground can cause wierd problems
