Dragster steering.
3 buttons I have 4 functions to hook up.
Trans brake to mega PB 1
SLC to mega SFO
Tap up/down to mega SFO 1
Reverse to mega trans
Heard SLC and tap can be used together.

Buttons
1-Trans brake
1-SLC/Tap
1-Reverse

Correct??
Thanks

Full instructions are posted online, but from memory, wouldn't your tap up/down be on P.B.2?

SLE and Tap Down use the same button input.

Tap Up/Down / SLE button should go to the 'Tap PB' terminal.

Your PB 1 and Tap PB buttons should have the 'other' wire going to Ground.

Your Reverse button should have the 'other' wire going to +12 volts.
