00' deville R/Startand keyless

ive got this car coming in a few days for a remote start, with keyless entry and trunk release, just wanted to know if anyone had any hints/tricks on the install. from what i know so far i need a GMDL2 for the doorlocks, and the car has passkey3, where can i get trunk release and tach?

That car is a little time consuming, but it's not nearly as hard as some of the tech sheets would make it out to be. I'll give you all my shortcuts, and then some regular tech information at the end. -If you want a strong source of constant power, there's a thick orange wire in the driver's kick panel that is suitable. -You don't necessarily need a module to do locks. The locks can be had as negative trigger, but you have to go inside the door. Disarm is in the door too---there are two similar-looking light green wires---one is for the power mirrors---so test carefully so you get the right wire the first time. -I've never had to power up the brown second accessory (radio) wire for remote start. -Parking lights is BROWN / white, negative, at the switch---I've never bothered chasing down the DIM module. -Trunk release is black, negative, at the release switch on the driver's side of the dash. Fuel door release is in there too if you look for it---I think it's pink? -Also, don't forget to set up your unit to disarm the factory alarm while the trunk is being opened. -Furthermore, I think an extended pulse to the disarm wire might roll down some of the windows. I'm not sure of this, though. Put the key in the driver's door, hold it to the Unlock position, and see what happens. -Tach isn't too hard. The coil pack is easily found at the top-rear of the motor, with four plugs, two large and two small. I know tach is inside one of the driver's-side plugs, but I forget which one. |       ITEM      |     WIRE COLOR     |POL|       WIRE LOCATION        | |              12V|orange or orn/blk *1|+ |ignition harness            | |          STARTER|purple or yellow    |+ |ignition harness            | |        IGNITION|pink               |+ |ignition harness            | | SECOND IGNITION|white               |+ |ignition harness            | |        ACCESSORY|orange              |+ |ignition harness            | | SECOND ACCESSORY|brown               |+ |ignition harness            | |       POWER LOCK|RED / black           |- |drivers door lock switch    | |     POWER UNLOCK|ORANGE / black        |- |drivers door lock switch    | |       LOCK MOTOR|gray               |   |drivers door module *2      | |     UNLOCK MOTOR|tan                 |   |drivers door module *2      | |    DISARM DEFEAT|tan                 |   |passenger door module *3    | | PARKING LIGHTS +|do not use          |   |                            | | PARKING LIGHTS -|BROWN / white        |   |DIM module *4               | |       HEADLIGHTS|white               |- |DIM module *4               | |     DOOR TRIGGER|*5                  |- |*5                          | | DOME SUPERVISION|gray               |- |underdash light             | | TRUNK/HATCH PIN|ORANGE / black        |- |trunk light                 | |TRNK/HTCH RELEASE|BLACK/ white        |- |under the rear seat *6      | | FCTRY ALARM ARM|                    |   |                            | |FCTRY ALRM DISARM|lt. green           |- |drivers door module *2      | | DISARM NO UNLOCK|                    |   |                            | |       TACHOMETER|PURPLE / white        |   |ign. coil on top of motor   | |      SPEED SENSE|GREEN / WHITE        |   |cruise control module *7    | |       BRAKE WIRE|white               |+ |low in drivers kick        | |     HORN TRIGGER|black               |- |DIM module *4               | |           WIPERS|white               |+ |DIM module *4               | | LF WINDOW UP/DN|dk. blue - brown    |A |drivers door module *2      | | RF WINDOW UP/DN|dk. blue - brown    |A |passenger door module *3    | | LR WINDOW UP/DN|dk. blue - brown    |A |LR door module              | | RR WINDOW UP/DN|dk. blue - brown    |A |RR door module              | | SUN RF OPN/CLOSE|dk. grn - lt. grn   |A |sunroof motor *8            | |   SUN ROOF LIMIT|red                 |- |sunroof motor *8            | |        RADIO 12V|orange              |+ |radio                      | |     RADIO GROUND|black               |- |radio                      | | RADIO ILLUMINATE|yellow/black        |*9 |radio                      | Notes: Note: This vehicle is equipped with the pass-key III immobilizer.
