I just thought I'd share this with you. For those who are curious about adjusting their TPS with L.E.D., then this is what I did this afternoon. Fortunately the whole process worked out fine. I only have one lamp on which means my TPS is adjusted properly. My total cost from this is (2 x $ 0.99).

By the way, as you can see, with this setup, I never had to use wires. Just stick those LED feet to the green plug and it should just work fine.

 

You just have to remember to get the positive and negative leads hooked up right. LEDs will only work if they are hooked up correctly, usually there is one lead is longer than the other. I think the longer lead is the one that you hook up to positive. In the TPS plug, I think the one where the two leads go in together is the negative (ground). Another handy thing that LED setup could be used for is a ECU code checker. I have the MAZDA special TPS adjusting lamp and I just hook that up to the code checking plug and get my codes with that.
