1995 model DEI 551T wires

I have been installing for several years and purchased some DEI equipment for my car. Then the car brokedown and I did not fix it. Now I have a new vehicle an am insalling the alarm in it. The alarm is a Sidewinder 5000, separate DEI 551T, and 530T, but I only have the installation manual for the Sidewinder 5000. Looking online at DEI, they only show the new 551T harness with one 12-pin, and one 8-pin connector, plus the relays connector. The 551T that I have has only one 12-pin connector and the relays connector. The wires are as follows(from top of module): 1- Black 2- Yellow 3- Blue 4- WHITE/ Blue trace 5- BLACK/ White trace 6&7- Grey 8- White 9&10- Brown 11- Blue/Black trace 12- Orange I do remember some of the wire connections, but since I left the Auto Sound industry and went to building fire, ambulances, and police vehicles, I have no access to the older manuals. If someone has the older 551T and 530T install manuals, please help me. LJ WolfLJ Wolf Co

Here are the wire colors for the 12 pin harness: black       - chasis ground yellow      - +12v ignition output to rf system blue        - (-) status output when active WHITE/ blue - (-)activation input BLACK/ white - (-)neutral safety gray        - (-)shutdown input white       - tach input tan        - (+) shutdown input blue/black - (-)ignition 2 output orange      - (-) accessory output

I have an older (95 era) 551t and I'm also trying to find the wiring diagram. I think dewwest just posted the wiring for a newer 551t. The older has 2 gray wires, and two brown wires. Why 2 ?? The first five wires, dewwest is correct. I figured those on my own. black is ground, yellow is ign output to the host alarm, blue is a (-)status output, WHITE/ blue is the activation input, BLACK/ white is the neutral safety input. I know one of the gray wires is a hood pin shutdown wire. But which one? and what is the other gray wire for? One of the brown wires I think is a (+)brake shutdown wire, but which one? And what is the other brown wire for? Also, I think the white is a negative parking light output, not a tach input(But theres a achance I may be wrong). Anyone have any knowlegde about the older 551t's?

No one knows about the older 551t's???
