Olds Intrigue: Remote start install help?

Hi All - 1st time posting here, so please let me know if I should be somewhere else! I have a 1999 Olds Intrigue and would like to install a remote starter. I have a DTI Readystart, a Prestige add-on and one that I designed and built for an independent study while I was in engineering school. I've installed two starters in the past; one in a Gen II Taurus and one in a Chevy Tahoe, so I have plenty of experience there. My problem is that I have no idea how to get at the wiring in the Intrigue! I tried taking off the driver's kick panel, only to find a welded-in-place steel plate. At the suggestion of a local install shop, I tried removing the radio and accessing the dash-mounted ignition harness from the side. No dice - more welded-in-place steel! I can see the wires from this approach, but I can't get at enough of them to actually make a connection. I also tried removing the glove box assembly, and there's a giant harness behind it (as well as lots of room for my somewhat sizable home-made starter board), but there are several of each color wire that far into the harness, so I didn't know which one to go for! The engine compartment is packed full, so no chance of locating the wires there. SO - any help with how to get at the ignition harness would be much appreciated, and also any suggestions on where to go through the firewall would also be wonderful! Thanks much in advance, D.

remove the under pannel 4 clips, unbolt the 4- 10 mm screws and unscrew hood and ecm dlc then you will se it all .just did one fun funfun

Lemme pick your brain a bit further - I've always been told those clamp-on splices are a no-no for high current apps. What's your opinion on these? I've always been all for the strip-it-back and solder in approach, but I can understand how you might not want to go that route if you're looking to get a car in and out of the shop quickly... eh?
