Your PCM contacts are probably already cleaned... Just take the keys out of the ignition, pull the PCM and slide the chip onto the board. Reinstall the PCM and turn the chip all the way to the right, and punch the go-pedal.

TS chips have a little ring in the switch that stops it at so many positions, I have a 4 position chip from tony and when I was installing the switch the ring fell out and I put it where I thought it was for 4 but put it was 5.

All of the knobs have that many positions, but that is only a knob, the chip itself only has room for 6. I think there are 8 position chips now though.

It's on the very left on your firewall. Try searching chip install or something similar. There'll be detailed step by step directions somewhere

then the knob to the left thats the first position which is prolly a stock tune, next just click it over one spot at a time. you should notice a different idle and shift firmness depending on whose tunes they are.

when u look under ur dash look to ur left. u will see a black box with 2 screws holding it. take the screws out and slide the box out. now it wont come all the way out to be carefull not to ripe the wires out. the box covering should slide farther back and there u will see how and were it goes.
