Ok, I got my LEDs and I put them in. But I can't seem to get the 74 bulb that lights up the 140mph mark to work. I took the old one out and tried to bend the wires around like the stock ones were as best I could...but it doesn't light up...

yeah i had a similar problem when i was trying to do it on my old Gen3...

i figured, i can get a 74 Bulb Holder, just like those other 74 bulbs in your gauge, it should fit

looks like this:

ok, I'll just steal the holder from one of the lights I removed...stupid high beam and cruise incicators...

flip the led 180 degrees in the socket. leds are a diode which only let current go one way =)

I think I trie that, but I'll do it again. Is there any way to see which way is which besides just guess and check?
