How do you hook a 700R4 TV/detent cable to a drive-by-wire LS engine with no throttle linkage?

Here is what the documentation says. Each point links to its source; details depend on your exact computer, harness and transmission.

Transmission control

• Bowler's Tru-Shift page states every kit includes GM round-hole, GM square-hole and Lokar throttle-cable brackets, and lists explicit incompatibilities: Quadrajet/Rochester/original-style one- or two-barrels, FiTech LS Fuel Injection intakes, and Holley Sniper 2.0/Dual setups. (Bowler Transmissions)

Throttle (drive-by-wire)

• 0411, 242; T56/TR6060, T5, TH350, TH400, Powerglide, 700R4, 200-4R; 1999-2007: PSI's Gen III 24x DBW controller kit for manual and non-electronic transmissions covers T56/TR6060 manuals and TH350, TH400, Powerglide, 700R4, and 200-4R automatics, and includes the same DBW pedal (ACC-1049), TAC module (ACC-1011), TAC harness (HAR-1022-C10), brake switch (KIT-1002), and tuned PCM (PCM-1005) as the automatic kit. (PSI Conversion)
• 0411, 242; 700R4; 1999-2007: PSI lists the 700R4 among the non-electronic transmissions compatible with its 24x DBW controller kit, so a DBW engine controller can coexist with a 700R4; the 700R4's TV/detent cable geometry is a separate mechanical setup not provided by the controller kit.
