Do not get confused between the large gauge wires that DO get connected, and the
small gauge wires of the same colors/function in the 4-pin connector that do NOT get connected in a 99 Camaro.
I'm not certain which style of heavy-gauge switching the 533 has. It is either an on-board relay package with a specific large-gauge harness, or a "Satellite Relay" package that is divorced from the 533 and attached with a 6-conductor ribbon cable. In either case, the heavy gauge connections are the same.
533 heavy wire == car side at ignition switch:
green == key side of cut yellow
purple == car side of cut yellow
pink == pink
orn == orn
(3) red, fused == red (all 3 can go on the one red. That's the way the car works).
pink/wht == brown (Program "FLEX relay" to ACCY function).
NOTE: Brown is the radio and wipers. These don't have to be powered during a remote start. If you do power them, the Retained Accy Power in the car will keep the radio on until it times out, or a door is opened. There is a work-around for this, but if the idea of the radio staying on for 10 minutes after a RS time-out bothers you, don't power the brown accy wire during RS. Another consideration (especially in Seattle) is that you may park the car with the wipers on because it is raining. But the next time you RS it, it may not be raining, and the wipers will be dry-wiping. Something to think about. (I do a lot of GM's. I no longer power the brown wire for a RS).
Thanks for the dinner offer. Unfortunately, I don't get up to Seattle any longer. I used to have a client with a yacht we serviced at Delta Marine every Spring, and I'd spend 8-10 weeks in So Seattle. I would become bored as hell, I would have welcomed the company. You can see Delta Marine from the 99 just before Marginal Way off ramp. There's usually several LARGE yachts on the river in front of the facility.
Cheers
