      I want to hook up Compustar 4900s with blade AL in Acura 2012 TL with PTS. But the starter wire really confusing me. I don't know how to hook up this wire. if the yellow wire pin 6 in cn1 not hook up then which stater wire output should i use? how can i start the car? I'm really stuck.  
 
  
Thanks for pointing out.

      You will use the CM900-s thick Yellow wire at CN1-6 for the needed (+) Starter wire.  While the Starter wire you are connecting to is much thinner, it is OK.  I typically cut the thick R/S Starter wire off about 4 inches and solder on a thinner, say 18 gauge wire, for the run to the vehicles Starter wire.
 
 The Type 1 wiring diagram is rather generic and shows the (+) Starter wire on the other side of the R/S controller and not grouped next to the other ignition wires.  Additionally, there are a few wire connections it does not show.  There are 2 Red +12V constant wire on CN1, both need to be connected. The Black Chassis Ground wire needs to go to a clear, rust free frame area.  If the car does not have a Factory Alarm with Hood Pin, you should install the kit supplied hood pin and make that wire connection.  The Horn is optional.
 
 Also note that the vehicle needs a (-) Parking Light signal, so you should use the thin Green/White wire CN3-1 for this, not the thick Green/White on CN1.
 
 Was the Blade AL cartridge flashed with the HA4 firmware?
  ------------- Soldering is fun!

      Got it, Thanks. The blade install guide got me good. I tried to find which wire on the other side i should use. Lost it anyway. I'll connect  like you said and will update later. The blade al got flashed with HA4 v1.4.
 Thanks again
