You are bidding on a NOS 30 Amp Relay Switch

Part# 15618

It is brand new in its packaging as shown.

The NOS power relay is designed to eliminate the high amperage current from damaging control components such as switches, microswitches, shift handle, buttons, etc. The power contacts in the relay will carry a maximum of 30 amps. Please pay strict attention to the switch wiring. If you have previously installed an NOS nitrous kit, you will note that the switches are connected differently. If you are upgrading your existing system, do not follow the wiring diagram from your original instructions. Use only the diagram shown here. Begin by mounting the relay close enough to the battery to allow the heavy 12 gauge orange wire that contains the fuse to be attached directly to the positive terminal of the battery. The ring terminal I.D. is 3/8” to accommodate the attachment bolt of the side terminal batteries. The battery post of the Ford style starter relay may also be used. However, you must be sure that the terminal, which is directly connected to the positive post of the battery is used. Complete the wiring by following the diagram below. Do not reverse the positions of the throttle switch or pushbutton (whichever you have) and the arming switch. If the switches are reversed, the light in the arming switch will not work correctly.
