its not the remote start its the car. with RS being universal it doesn't know what kinda car its going into, plus its in the GM era saabs. I've done one saab in my 30+ yrs career and told my self ill never do another, and I haven't since late 90s
directech say this
Accessory 1 can be connected with brown accessory 2 just use 2 diodes to isolate
Ignition 3 can be connected with white Ignition 2 just use 2 didoes to isolate
ignition 1 is pink standard hook up
starter is yellow standard hook up
key sensor is lt. green (-) standard hook up from status output from remote start
wires colors are the factory colors not the RS
I'm a little confused on the wiring with the diodes. This route would avoid having to program the CM900 correct?
Accessory 1 (CM900 CN1 Pin 4?) [WHITE] to Accessory 2 (9-7x) [BROWN]
Ignition 3 (Where is Ignition 3?) to Ignition 2 (9-7x) [WHITE]
How do 2 diodes connect to 2 wires that connect to each other? Apologies for my cluelessness.
Accessory 1 is on the CM900 correct? Where is Ignition 3? I don't see it listed in the CM900 manual.

Ok, I see about the diodes. I was confused why you would tie two together on the same wire.
So how would the wiring be with the 2 sets of diodes? Just making sure I have this right.

just like a y adapter. wire coming from the RS brain goes to the 2 diodes same end then the other side of the diode goes to the accessory 1 wire and the send diode goes to the accessory 2 wire
31 years as a installer. Favorite thing to install/topic are remote starts/car alarms. Stop using test lights!!!

Here is how I would do it with the CS4900-s w/ CM900-s controller and Expresskit GMDLBP Bypass Module without having to change any CM900-s POC's. You will need a couple 1N4001 diodes and a couple 6 Amp diodes.
The main ignition harness connections will be made at the switch in the center console. It is a Black 12 Pin plug.
CN1
Pin 1 Red - Constant 12V...........................................Orange (30A) (+)....@ trailer brake pre-wiring on harness going thru driver firewall *
Pin 2 Green/White - (+) Parking Lights............................Not Used
Pin 3 Red/White - Constant 12V....................................Orange (30A) (+)....@ trailer brake pre-wiring on harness going thru driver firewall *
Pin 4 White - Accessory 12V positive (+)..........................split wire with 6 Amp diodes, bands away from CM900-s - diagram below
Pin 5 Blue - Programmable Output...set jumper to IGN.....White (+)...........@ ignition switch, Black 12 pin plug, pin 10
Pin 6 Yellow - Starter 12V positive (+)...........................Yellow (+)..........@ ignition switch, Black 12 pin plug, pin 11
Pin 7 Green - Ignition 12V positive (+)..........................Pink (+)............@ ignition switch, Black 12 pin plug, pin 5
Pin 8 Black - Ground negative (-) input..............................Chassis Ground
* Change CM900-s fuses to 15 Amp fuses
Accessory 1 = Orange (+) @ ignition switch, Black 12 pin plug, pin 7
Accessory 2 = Brown (+) @ ignition switch, Black 12 pin plug, pin 12

For the Keysense wire you will use the CM900-s Black (-) GWR (Status Output) wire. It is already being used to control the GMDLBP bypass module so 1N4001 diodes are needed to provide isolation.
CN3
Pin 4 Black - [POC 4] (GWR) 250mA latched (-) output.......wire as per diagram below
Keysense....Light Green (-)....@ ignition switch, black 12 pin plug, pin 4
GMDLBP......Brown (-)..........Status Input wire

This is amazing.
It turns out I didn't have the ACC2 (brown) wire connected to the CM900 after going through my notes.
Thanks for all the help!

Here's a list of the connections I made into one page. It didn't copy very well from word so please excuse the weird format. I believe I had the Factory Disarm wire from the CM900 connected at one point to the GMDLBP but that was causing issues so I put it back to normal. Not having the ACC2 wire connected might explain why my starter went out last summer. Have you seen the ACC2 wire not connected cause that?

Possibly. Here is the note about the ACC2 wire.
Must be powered up. If not, the vehicle will crank as soon as it sees ignition.
I don't use GMDLBP bypass modules, so I don't know if this will solve the Security Light issue. Proper Keysense control might.
If you want the R/S to control the Parking Lights, here is the info :
Parking Lights (-)......Brown/White (-).......@ steering column junction connector, Black 48 pin plug, pin E7
CM900-s   CN3 Pin 1   Green/White (-) Parking Light Output

Ah good. I had that connected already.
I have to order the 6 amp diodes but I’ll get this all setup once they’re here. Do I need to reset the CM900 or bypass module? Just making sure.

CM900-s should be OK. The GMDLBP factory default is Type 1 and if it programmed to the Saab OK it should be fine after you feed the diode isolated GWR signal to the Brown wire.

Everything is working correctly now. The keysense wire wasn't hooked up to the remote start at all.
Thanks again for all of your help!
