Dudes,

I just finish installing my ZEX race nitrous system, eveything is OK, less one thing.

It came with a TPS activation module.

In the ZEX diagram states that the white wire should go to the TPS output voltage wire!!!!

My TPS has 4 wires, a b c d.

Don't know where to conect.....any lights out there.....

Thanks in advance

Gabe
