Can I rewire by slicing into the wires - they are all running together in the garage attic - and reworking them thusly:

Let's call the 4 wire pairs going to the garage bays A,B,C and D

and the 4 wire pairs going into the M1 - W, X, Y and Z.

And we'll number the wires 1 and 2. So A1 and A2 go to the sensor on garage door one and W1 and W2 go to zone 1 Neg and ZN-1 on the M1.

Now I take the wire pairs at the M1 and rewire them thusly:

W1 goes to VAUX neg

W2 goes to VAUX +12 Volts

X1 goes to zn 1

X2 goes to zn 2

Y1 goes to zn 3

Y2 goes to zn 4

Z1 goes to trigger for Out 7

Z2 goes to trigger for Out 8

Now at the splice I do the following.

Run a new 2-pair wire, R, to the relays (Elk 924)

R1 - goes to relay 1 +12V and to relay 2 +12V

R2 - goes to relay 1 Neg and to relay 2 Neg

R3 - goes to relay 1 T+

R4 - goes to relay 2 T+

And I connect the wires thusly:

A1 goes to W1 (VAUX neg)

A2 goes to X1 (zn 1)

B1 goes to W1 (VAUX neg)

B2 goes to X2 (zn 2)

C1 goes to W1 (VAUX neg)

C2 goes to Y1 (zn 3)

D1 goes to W1 (VAUX neg)

D2 goes to Y2 (zn 4)

R1 goes to W1 (VAUX +12V)

R2 goes to W2 (VAUX Neg)

R3 goes to Z1 (trigger for Out 7)

R4 goes to Z2 (trigger for Out 8)

Will this work??
