Pretty straight forward, wiring as shown in the pic I posted. Just match up your terminals as shown in the pic I posted. You can mount the new IVR where the old noise supressor used to be. You will need to pull your fuel gauge out, remove it's gauge face, then remover the gauge electronics cover and disable your internal voltage limiter by simply bending back the bimetal points arm be sure it is clear of touching anything. Reinstall your cover, gauge face plate and then your gauge into the housing, then wire your new DemonIVR as shown in the pic
