yep look hard wrap very carfully and please know what your doin. theres a little opening under the dash where the steering wheel is to go from the engine to the car compartment, so theres your in and out. your ground is always the frame and your positive you gonna have to look and see what fuses you can tap but make sure you have an adapter with a fuse so you dont blow anything. hope that helps and cant wait to see what youve done.
Good Luck
