Puttin an '04 Throttle by Wire 5.3 into my '01 Throttle by Cable 4.3.

I purchased a 5.3 cable driven throttle body thinking I could just hook the cable up and not hook up the TBW connectors that are on the '04 harness. Here is my problem. The TBW connector is 1 connector and this cable driven TB has 2 totally different connectors (1 for IAC and 1 for TPS). Now realizing that I'm an idiot....

CAN I MAKE A SEPERATE HARNESS from the cable driven throttle body (IAC and TPS) to the '04 PCM and just repin it according to an '01 5.3 PCM wiring diagram? Cross my fingers and hope it works? Is this even possible without having to find either a TBC harness and PCM OR a TAC module and pedal?

p.s. sorry if i'm not making damn bit of sense...
