The factory highbeam relay is a mechanical toggle relay. As they get old, they stop working correctly. It takes multiple pulls on the colum switch to engage the highbeams. Some may stop working completely.
Below you will see how to wire up an electronic relay. It's very easy to do. The very smart European builders have standardized their relay terminals. So many manufaturers relays will work. The picture below is a Saab relay. This relay can be found for $5-10 at junk yards. The 914 relay is about $50   You will need to jumper terminals 30 and 86 together with the 914 wire from terminal 30 Terminal 56a will go to the 914 Yellow headlamp wire Terminal 56b will go to the 914 White headlamp wire Terminal S will go to the 914 wire from Terminal S The final wire will be a new Ground wire you will add to terminal 31 That's it! You will now have an electronic highbeam relay. Now you have to figure out how to mount it. |
