Converted vehicle: 1986 Holiday Rambler Imperial 33'
Mark IV 454 4bbl/TH400
The current VSS(signal generator) on speedo cable at trans is (59D-02392-1 / 8ppr).
Donor vehicle: 1993 C3500 HD
Gen V 454 TBI/5 speed
Currently using ECM 1228747 ARPA that was pulled from the '93.
Also have an AKWA and ANRS available. These might make a difference with the 454 and TH400 ???
TBI conversion went smooth and vehicle seems to operate normal after 30 miles of road tests. (loop status functions seem normal with no codes set)
I'm using the 1993 OEM cruise control module for this conversion and not sure what type of pulse signal it requires ? Also what the ECM requires ?
I don't think the current VSS/pulse generator(59D-02392-1 / 8ppr) will send the correct signal to the DRAC and then on to the 1993 cruise control module and the 1228747 ECM.
Below is a list of pulse generators shown at http://www.jagsthatrun.com/Pages/Spe...eedometer.html and I need help choosing the correct one for my application. According to the year models shown it seems like #3 should be the choice, but I just want to be sure because they are rather expensive, so any advice would be most helpful!
1. The two-pulse (2000 pulses per mile) square wave(D.C. current or direct current) used on all TBI engines through 1992, all computer-controlled-carbureted engines, and on 1985–1989 TPI engines.
2. A four-pulse (4000 pulses per mile) sine-wave (A.C. current or alternating current) signal is required by the 1990–1993 TPI, 1992–1993 LT1 engines, and 1990–1993 Camaro 3.1/3.4 V6 engines.
3. A 40 pulse per driveshaft revolution speed sensor used on 1993 and newer trucks with automatic transmission, 1994 and newer rear drive cars (Camaro, Corvette, and Caprice) with the automatic transmission.
