Interesting,
Not sure what state my relay is in, it may well be the original one which could mean I am running on borrowed time.

What is this relay?

The relay is what switches the power to run the suspension conpressor. Rumours abound on the line about the contacts fusing together making the compressor run continually till it burns out. It's tucked away behind the dash sonic it fails you can't get to it to pull it out quickly hence the idea to go solid state to prevent the issues mentioned
