Test Bench

[vsslpr]

Hoping someone can help with wiring up a test bench for a VS V6 Auto. I have done the following so far:

Power-
PCM Pins A1, A2, B1, B2 ; Negative terminal on PSU
PCM Pins A8, B8 ; Positive terminal PSU

Data Connector-
ALDL Connector Pin 9 to A3 on PCM
ALDL Connector Pin 5 to Negative PSU terminal
ALDL Connector Pin 6 to B3 PCM

I have the NVRAM board plugged into the PCM and ALDL connector plugged into the PC. TP5 will not detect hardware...

What am I missing??

PS I am trying to test an auto 728 PCM that I have converted to manual using the info at this thread: http://pcmhacking.net/forums/viewtopic. ... 7&start=40
(The NVRAM has the latest Enhanced BIN written to it but no manual flags checked so still in auto mode - does this have any effect on why its not working? Or have I just cooked the PCM during conversion...? LOLL)

Thanks in advance!

got vats off?

Pin B3 is intake temp sensor, only need the other two wires.

[VL400]

Pin A4 needs ign switched 12V.

Pin B3 does not need any connection for data to flow.

Otherwise should be good to go

Thanks for the help guys!! Re-burnt the BIN file with VATS off and Manual flag selected and added pin A4 to +12V terminal
got it going and good news I have successfully converted my auto to manual PCM! confirmed it works now
