Brake Switch Hookup, AAW

[ls1nova71]

To wire up the brake switch pictured, you would hook the first set of contacts, the two closest to the plunger, to the orange wire and the white wire. The orange should be a constant hot, coming from the fuse box, more precisely the brake light fuse, and the white wire will go to the brake lights, although generally not straight to them, as it will usually go to the turn signal switch first. The second set of contacts, the furthest from the plunger will go to the TCC wire in the PCM C1 pin 33 on one contact, and then an 'ignition hot' on the other one. You don't want the torque converter to be on a constant hot circuit. If you are planning on using cruise control, you will also need to hook up the pin 6, light blue wire in the TAC module harness to the white brake light wire.

Thanks Nova, where does the relay wiring from the switch on the trans go to or is it separate of the brake switch?

The NSS is completely separate from the brake switch in a swap. The factory uses it for a shift interlock, but you most likely dont have that.

Ok, I thought they were tied together, thanks!
