Here is a simple schematic of the circuit that GeneralDisorder described. I have not confirmed two things: 1. The Bosh Part Number for the relay 2. The amperage of the fuse between the battery and Pole 87 on the relay. Ignition Relay Schematic.pdf

Thanks again for all your help GeneralDisorder. Here is a Bosh Relay that I think will work. It seems to be a 30A dual circuit NO relay with both circuits closed when it is activated. Only one side would be needed for this application. Bosch 332019150 Relay It appears to be marked with the Pin numbers you described in your post: "Yes it's very simple. Battery positive (through fuse) to normally open relay contact (pin 87), relay contact common terminal (pin 30) to starter solenoid, tie the old solenoid wire to relay coil positive (pin 85), and relay contact ground (pin 86) to chassis ground." If you could confirm that said relay will work, I can draw a quick electrical schematic and post it so as to assist others that might be wanting to do the same thing. The link below is where said relay could be found on Amazon to anyone so inclined. https://www.amazon.com/Bosch-332019150-Relay/dp/B0010ADJIE/ref=pd_day0_263_1?_encoding=UTF8&psc=1&refRID=89J2X94MX54ZC7J4EK12#Ask

Hi all- Here is a starter relay I believe will work. You will note that the poles are labeled for the various wires needed. I have not tried this relay yet. https://www.napaonline.com/en/p/ECHSR15

Thank you all for replying. Does anyone have a schematic of the relay installation? Also if anyone has a link to the YouTube video of the removal of the ignition switch, I would appreciate a direct link. Searching YouTube yeilds far too many non-useful results.

I have a 1988 GL10 Turbo Wagon. I have an intermittent starting problem. It starts several times and then it does not. All power comes on and there is a slight click but the solenoid will not engage. I continue to turn the key to start and after 10 or 15 attempts it will engage. The battery is new and the charging circuit is operational. I replaced the starter with a new - not remanufactured - starter. The problem continues. I am now pretty certain the actual ignition/key lock switch is bad. How do I remove it? I have a tilt column. I have heard there is a video on YouTube but I cannot find it. I am ok putting in a new switch and key keeping the old key for the doors but I might have the tumbler keyed to the old key.
