sounds like the same problem i had lol. how did you wire it up? how did you set the WOT on the box? i can help ya out. heres a pic of how i wired mine up and ive had zero problems with it. the wiring on this diagram is right on, the only thing is, you need to run the tps wire from the NMU straight to the throttle position sensor first so you can program the WOT switch on the NMU. after you do that, cut that wire, and you can hook the tps sensor wire to relay and nmu tps wire to relay. lemme know how you made out buddy.

 

98TADRIVER,
I can't add pics but I can fax it to you if you want. I also have the ZEX Traction Controller on mine. I wired the red wires from both thru the relay box and the white wires go from the NMU to the traction controller and then to the TPS blue wire. And both are grounded to the factor ground under the hood. Any help would be greatly appreciated.

98TADRIVER, Spoken to ZEX today and they had a few things to check and I had a loose connection at the TPS. So I soldier the connection, checked the ground and the TPS amp. And it works great!!! Thanks For the info I really appreciate it.
