Fuse panel 1986 G and M Connectors

 Fuse panel information... the start of a collection.

“G” and “M” connectors on 1986 fuse panel

The group of (mostly unused) spade connectors on back of panel have some interesting properties, especially G10. There is a diagram in the Bentley Manual illustrating the terminals, and they are number on the fuse panel itself. Here is what I decoded, on an 1986 Syncro GL. 

G1 – X bus controlled power, fused through S12 (20A)
G2 – #15 ignition switched power fused through S18 (10A)
G3 – X bus controlled power, fused through S12 (20A)
G4 – D+ alternator trigger circuit via alt. led light
G5 – #15 ignition switched power fused through S18 (10A)
G6 – dead end
G7 – power when headlights on
G8 – dimmer controlled dash light power
G9 – license plate lights power fused through S20 (10A)
G10 – power when windshield wipers run

and the M connections close by:

M1 – connected to G7
M2 – power with lowbeams
