Well, I've finally put in the 7730 last weekend, basically rendering my DashScan useless. So now I have to start working on a solution... ;-)



Awesome!

I look forward to seeing your work!

whats the word on the 10268461 shock sensor? also, what is the potentiometer knob coming out the side of this?

Most likely to set the sensitivity of the sensor... you don't want a strong gust of wind to set it off.

But I gotta test the train horns one way or another

Anyone want to buy a BCM and 2 remotes for the F-Body:

BCM pn: 09353691
Remote pn: 16245100-29
I bought them both off of EBAY wanting to test them out, but didn't get around to it. Price is $90 shipped anywhere in the US. First email to mcgavinz26@gmail.com gets it. I bought these and have not tested them, but I have no reason to suspect anything is wrong. Ebay seller stated they were in good working order and had good reviews.

And to mix up the conversation even more, I did put a BCM in my Fiero, but it was from a 2000 Blazer.
Wiring diagram: http://s16.photobucket.com/...=FieroBCMharness.jpg

Pros:
This does not require taking apart the dash to install.
If you unplug the BCM, your power locks, horn, and lights still function as normal.
I found a way to wire it so that most (all but 5 wires) of the wiring gets plugged into the car's harness, not spliced. This makes installation easier.

Cons:
No flashing alarm light, but the alarm still works. Adding a flashing LED is pretty easy, doesn't need to be part of the BCM.
No shock sensor.
Not all of the BCM's of this generation have the alarm function, which was my main reason for doing the install, but I didn't find this out until later.

I am gathering all the parts together to tackle this and here is what I have:
F-body BCM
Three connectors with 6-12 inches of wire
F-body shock sensor
Two new key fobs
Extra wire (F-body dash & interior harness)
F-body factory service manual
P-body factory service manual

I need the pins and the tool for removing the pins. I re-read the website and am confused. What part numbers are for the correct sizes of pins and how many are needed of each? I will get extras anyway, but do I need 5 or 20? Anybody know the best place in the US to order the pins and the tool for releasing them?

You can still get most pins at www.pcsconnectors.com. Ballenger Motorsports has the removal tools: www.bmotorsports.com.
Hope this helps...

I know it is an old thread, but I recently started this upgrade. I skipped the rear hatch wiring because I was a bit confused. Why all the wiring at the switch? Since we already have a rear trunk relay, I wondered why we don't just tap into the relay signal side and run that to the correct terminal of the BCM? I did not do that because I figured there was a reason Fieroluke didn't do it that way, so I just didn't wire in the rear hatch release. Any information on why you did what you did for that part would be appreciated.

I'll be doing the tests tonight, so we'll see what happens... cross your fingers for me!

Well, the Fiero trunk relay can't be used with the BCM upgrade because it's only a 3-pin relay like the horn relay. On the FIero all solenoid power goes through the trunk release switch. The relais is only for disabling the trunk solenoid if the e-brake is not pulled or the transmission is not in PN.
The BCM can't drive the trunk solenoid directly, but it only has enough power to drive a relay. Since the 3-pin relay is not compatible with the BCM in this circuit, a 4-pin relay must be used with the BCM (if you want to be able to remotely pop the trunk that is). You could wire the 4-pin relays working contacts in parallel with the trunk switch, but then you'd end up with 2 relays where 1 would suffice. That's why I went with the schematics as they were on the f-body.
