550esp rs relay satellite

1987 Buick Grand National DEI 550ESP The wiring in my car was getting out of control with all the gauges, stereo and alarm stuff I have been installing over the years so I decided to do some spring cleaning. I have read and read and searched and searched...I can't find the answer to this one...I believe I am just not seeing the forest for the trees... My remote start relay satellite is just like it should be, except, I have THREE orange wires connected to my accessory relay. 85 - orange wire from 5-pin harness 86 - red 12v jumper wire connected to all relays 86 and 3A fuse to 2nd IGN relay, 87. 87 - red 12v 30A fused to constant power source (also jumped to starter relay 87) 30 - orange to "run" - which in my car is orange (although the install manual says this should be "accessory") But what I don't understand is, I also have 87a - orange to "run / accessory" - which in my car is brown. So, when the relay is at rest, the two orange wires ("run" and "accessory") will be closed. And when the relay is energized, the "run" and "12v constant" wires will be closed. Not sure why this is, and was hoping someone could explain it to me... I have enclosed a diagram for reference... TIA! Shawn

In you car, the orange wire is hot in RUN, but powers the Climate Control and Power Windows. It is an accessory circuit, in that it is not powered up in START, but isn't powered in ACCY either. So the orange wire should be treated as an Accessory Circuit by depowering it in START to remove the blower load while cranking. The wire for RUN (Ignition) is the Pink wire at ignition switch. What the 87a connection on Relay #2 does is allow your power windows and blower motor to operate in the ACCY key position. But your Brown Wire ACCY circuit (radio, wipers, cruise control) will NOT be powered during RS operation). This took me awhile to figure out. You can leave it the way it is, if you like the way things work. (PW and Blower in ACCY, and no radio in RS). ````````````````````````````````````````````````````````````````````` I just did a 551T in a Syclone a week ago.(A GN owner knows what a Syclone is). I believe the relay packs are identical. Your diagram colors are same as my relay pack, so this should work for you too. Here's how I did it: In your diagram, relay #3 (IGN 1) and relay #4 (IGN 2) have a common trigger from the 5-pin ribbon connector (pink). At the 5-pin ribbon connector swap the positions for the pink and orange wires. You now have 2 ACCY relays, and 1 IGN relay (the former ACCY relay #2 in your diagram). After the swap, connect the heavy relay output wires as follows: Relay #1 (30) Purple to Yellow (START) @ ign switch Relay #2 (30) Orange to Pink (IGN) @ ign switch Relay #3 (30) Pink to Brown (ACCY) @ ign switch Relay #4 (30) Pink/Wht to Orange (HVAC & PW (ACCY2)) at ign switch. Lastly, document these changes in your installation manual so another installer or yourself will be able to figure out what you've done. Please let us know how it came out. Cheers.

here is brand new 550ESP relay bank. The only relay that has a wire on the 87a terminal is the igintion. That wire is for the alarm to sense the ignition when the RS is NOT being used. It was a clever was to remove the wire from the circuit and eliminate false alarms when remote starting. Where did you get your relays from? Were they possibly made for another model RS? yuk

If your system moves you physically and not emotionally, you have wasted your money.

if the relays are wired as you say, then once connected, whatever is on the orange 87a wire would be on all the time.yuk

That's what I thought too. Then I looked at it again. (B+) is on terminal 87. (Not 30). So 87a is not connected to B+ when the RS is not active. (Relay at rest). It's a weird way to get the HVAC (car orange wire) powered up as an ACCY circuit, and get the power windows to work in key-in-ACCY, but that's what it does. I forgot about the yellow wire on 87a of IGN relay for the alarm. Thanks. If his GN uses that wire, my suggestion requires incorporating this wire.

i see that now.yuk

i would remove any wire that is not yellow from all 87a terminals and live happily ever after.yuk

Hello and thank you for your reply. I like things the way the are, so I will keep it as is... BTW, I have no yellow wire...I have the FSM and I don't see it there either...Shawn

Thanks for your reply. My relays don't look like that. They look like the ones I my diagram... FWIW, I have read up a lot on these...and I do see some differences (albeit rare) in some of the harness. For example...my starter kill relay does not have the green and black wires...it has orange and black instead...Shawn
