Wakespeed make positive and negative wiring harnesses depending on which type of alternator you have. In the US alternators are typically P Type and need a positive harness. In Europe alternators are typically N Type and need a negative harness. Since we are in the US PKYS only stocks the P type harnesses but can special order the N type when needed.
You also get to decide on the length of the harness and that depends on where you plan to mount the regulator. The Standard Harness (WSPH) is pprox. 5 feet long, typically used in marine environments where the regulator is mounted close to the alternator in the engine room. There is usually room to mount the regulator there. The Van Harness (WSPHVAN) is approx. 26 feet long, designed for vans where the regulator is usually mounted further away from the engine (near the house batteries) to keep it clean and dry. There is usually nowhere in the engine compartment to mount a regulator
