How-to Circuit: Install Opel GT Protective Ignition Relay
Sponsored LinksIf you need to diy install a protective action for securing your Opel GT ignition switch, and you might install a protective 4-prong
30 amp relay in the starter circuit, the following circuit schematic may guide you for installing this relay.
You need to assemble a harness, with 3 short wires, 4 clip ends and 2 eyelet connectors for connecting 3 relay terminals, one solenoid terminal, one round solenoid battery post, and a round ground on the chassis. The existing ignition connection will be transferred from the starter solenoid to the new relay as seen in schematic. You may place the relay above the starter on the under-hood side engine area.
The relay will take up the brunt of the current when the starter is powered, keeping it out of your valuable original GT ignition switch. Completed circuit guide on How to Install Opel GT Protective Ignition Relay can be download in pdf (source: opelclub.com)
