I recently installed a Painless Wiring Hot Shot starter relay kit in my 4Runner to cure an intermittent starting problem. While my starter solenoid contacts were in good shape, I would still get an intermittent "click" when I tried to start the engine. Since my '85 has no starter relay of any sort, the ignition switch provides power to the starter solenoid directly. After 19+ years of use, I figured it was getting tired. So, by adding the relay, I took the heavy current load off the ignition switch and let the relay handle it. Installation was a snap, clip the wire running to the solenoid and run it to the relay coil, then the output wire of the relay to the solenoid and finally run the heavy relay power wire (via the supplied circuit breaker) down the the 12V post on the starter. The relay kit includes an engine "bump" switch which allows for bumping and starting the engine from under the hood. I may also run a second switch in parallel back to the dash to use as a starter button for on the trail. Take the wear and tear off the old ignition switch and make it last as long as possible. Since installing the Painless relay kit, I've experience no more starting problems, it cranks as soon as you turn the key every time. The wiring of the Painless relay kit is very much like shown below. To install it all you need to do is to cut the wire running to the starter solenoid and splice in the relay. I used connectors to tie in the relay, the incoming signal (that originally came from the ignition switch) is run to the relay coil, the output from the relay contact is tied into the remaining wire at the solenoid. Only other relay kit connections are a chassis ground and constant power from either the battery or the starter power terminal. The kit includes a circuit breaker to protect the relay and wiring from over-current.
