I have a MSD 2step 8733 and need to know how to wire it up with my trans break to build boost. I was told I need a 5 pin relay to use. I just need to know how to wire it up with a positive activation. Please help.

 

Im installing mine this weekend. Why would you need a relay? I guess if your momentary button isnt rated high enough. But im going to hook mine directly to the positive side of the transbrake solenoid so it activates off the same button. Dont see why this wont work

 

You need a 5 pin relay if you are going to hook up spray. you run the WOT switch on the normally closed contact and the coil of the relay on the TB circuit. this way when the TB is activated it interrupts the WOT signal
