wire/lamp identity??

That lamp tells you one of two things when it comes on. 1) the parking brake is on, or 2) there is an imbalance in brake pressures between the front and the rear systems.
-Well, if you have an auto, you practically never use that brake. And if you have a stick, its second nature to release it before moving off.
-As to its purpose as a brake failure indicator, Hah! Since it comes on after the failure has occured, it doesnt tell you much that you dont already know, as you panic brake on the remaining system.
-My bulb has been burned out for years, and Im in no hurry to replace it.
-What you do is up to you. Nice cluster BTW.

Ya, I see what I did. If you look at the new cluster, there is a red LED. I picked up that LED with the dark blue at the round main plug connector and ran the black to the parking brake push button switch. What I did not realize is that the dark blue also powers up that warning indicator. So I guess the blue with white trace goeas to that proportioning valve and if I want that to be workable I can take the blue with white trace and twin it into where the dark blue goes to that LED, so it will light that instead of the original bulb?? Does that make sense??? I probably won't do it, but I am just wanting to understand the system. You are right, it lights after the failure, which should be noticeable to the driver anyway..

Hey thanks AJ. Electrical is not my strong suit. Actually, I am not sure I have a strong suit...LOL.
