According to the 93 Helms manual (I know you're asking about a 94).
The TPS Module is located on the right side next to the blower case.
The Module is used to allow the EBTCM to read the TPS signal.
The EBTCM uses the signal for determining potential adjuster assembly requirements for engine torque management.
The TPS Buffer Module
1) Scales the TPS signal.
2) Resolves ground differences between the ECM and EBTCM
3) Buffers the signal so the TPS signal to the ECM is not affected by the EBTCM.
The 93 manual shows the location of the TPS Module in the same place as the diagram you posted for a 94. Two bolts mount the TPS module to a bracket that appears to be bolted to the firewall.
