Dual Resistor - WHY !?

danishcarnutMember

I was wondering about the dual resistor on my Pantera. I've seen resistors before, ofcause. But only where the positive (hot wire) from the ignition runs through on it's way to the coil. But never seen a dual, where it seems like the negative also runs through it... WHY !!???
The negative wire (Light blue) from the coil must feed the tach, right ? Does it need to run through that resistor, or how does it Work ?
I see the blue and red wire from the dual resistor goes to a plug, where the blue splits to a Blue wire and a Dark blue - The red splits into Red and Pink wires....

I simply don't get it !!!

I have the POCA Tech CD, but think the wiring diagram on that disc is hopeless. Anybody that have a link to a better wiringdiagram (Late Pre L)
