02 Pontiac Grand Prix, Viper 5704

The problem there Kregg is that some of the wires have different functions, second unlock on 5901, gone by 5904. I think your new name might well have to be either Kregg.22 or Kregg Airsoft.

Actually my grand prix is a 4 door. Hopefully these directions are for a 4 door and not just a 2 door.

None, except double the connections and diodes.

Also I wanted to get a little electrical tester. But my question is do I need a continuity tester or circuit tester. it was in 1 of the bulldog videos it lights up when you have the right wire or something like that.

Get a DMM with a 10 or 20 amp AC current tester. A bulb tester would be dangerous for someone who like yourself isn't sure. No insults intended but your questions bear out your levels of experience/skill. You shouldn't even consider attempting a job like this with at least the following:= Soldering iron solder heat shrink sleeving required extra cable diodes relays insulated tape AND Scotch 33+ for the solder joints you can't sleeve DMM from Sears, Radio shack. Philips screwdriver 1/4" socket set 6-13mm side cutters quality crimper (not $3 in Walmart) strippers Stanley knife cordless drill driver and 2.5mm and 7mm bits (3/16" and 9/32") assorted size Philips and Torx bits for above I wouldn't even consider making a joint without first testing.

Are there digital multimeters that I can poke the wires with instead of having to strip it? And by the way I have wired a car radio before.

A good quality DMM and a set of "Bed of Nails" test leads will work well.  Search on "Bed of Nails" for pictures of these leads.

You have chosen a very sophisticated alarm system to install.  It will require a lot of research, reading and learning to install properly.  It will provide an excellent learning experience.

Soldering is fun!

Craftsman at Sears, DMM 0348234400 about $32, "bed of nails" alligator clips (or croc in the UK) about $20, but go to a Sears and look around. Solder Portasol by Weller about $90 Irish and I never liked them especially when they used to be sold by Snap-On, Bluepoint badged for about $150 or for a one-off, Portasol mini for under $16. I personally use Weller Pyropen and Pyropen Jnr., but the US price is believe it or not 50% more than the UK!! Craftsman lists them as about $140 and $170, the UK prices are $90 and $110.

I got the bed of nails test lead adapters and going to borrow my dads dmm. And I already have a Weller soldering gun and shrink tubing and wire strippers. Anything else I'm missing?

No you're basically there, other tools:= Trim poppers if you have to remove trims. "Bojo" plastic trim tools. T20 Torx bits. Ref the Weller prices:- STA-1 (Now WP60) $80. Junior $72.
