Brake Light Override; I'm seeking answers

My sedan is starting to take shape and I'm at the point where I have to mount taillights and such. The problem I have is I need to know how to wire them so i have only 1 1157 bulb per side,ie 1 taillight per side. I have a Signal Stat 900 turn signal switch but i do not know if it has a brake light override built in. Without an override of some sort when I have the turn signal on and step on the brakes, the light will quit flashing...right? What are you guys doing to make your systems work?.....Thanks....Mike

 

if i remember correctly if it has 7 wires it will have the brake light override. i sorted the wire by using an ohmmeter and tracing thru them with it set to the right and left positions.

I'd have to out the garage to be sure but I remember mine only having 6 wires. I remember looking at the schematic and the switch and seeing it had only 6 wires and not all the same color as the ones on the schematic(which has seven). The switch has "Signal Stat 900" right on the face. Did Fedral Mougul make a cheaper version?

 

A model 900 has at least 7 wires, some of them have more. A model 700 has only 4 wires.

 

turn siginal switch,

LF
RF
LR
RR
brake feed (from the brake light switch)
flasher feed (from the flasher)

if you have a seventh wire it may go to the flasher, depends on if you have a 3 blade flasher or a 2 blade flasher

so you would run the wire from you brake light switch to the turn siginal swith to the brake light feed wire, and the wire(s) coming form the flasher would go to the flasher feeds.

the other four are self explanitary!!

but if you run turn signal indicators you need to run them of of the front signals or elso thell light up when you hit the brakes.

 

oh yeah, when you hook up you tailights, jsut make sure the right rear and left rear (coming from you turn siginal switch) are hooked up the the brighter eliment on the 1157 bulbs.

hope this helps

 

hERES THE SCHEMATIC

My switch

6 wires

Mine has an orange instead of grey and no black/grey(stop light switch)

 

If you want a trifle simpler indicator, wire the turn signal indicator (the dash repeater) across the front two power leads. In other words, run one wire of the indicator bulb to the left front indicator, the other wire to the right front. The indicator will blink for either turn signal, so you will have to remember WHERE you are going.
This works because the blinker filament that is not being used provides the ground for the dash indicator.

I dont know but the schematic looks wrong!! Id jsut test it so find out how to hook it up.

with the turn signal switch in the neutral position 3 of the wires should have continuity, those would be for the brakes, one being the brake feed, the other two being the the brake light/turn signal, then you have to determine witch, turn the switch to one direction, find the one that goes dead, that would be either the opposite stop light in the directrion you turned the signal switch, or the brake lite feed, remember that wire, then turn the switch to the other direction, while moving the test lite to the other wire and if it doesnt lite up, then you found the brake lite feed, then you can put the test lite on the brake feed and test the wires back and fourth and mark the direvtions on them, remember the one that lites up is the opposite direction you are turning the turn siginal switch.

Dunno if it came out right, it makes sense in my mind, now let me think how to test the flasher feed and front turn signals

Thanks for the help guy's. I'll have to do some testing......Mike

 

The brake light override is built into the black box. I think you might be making this deal harder than it actually is...... Use the manufacturer's schematic and go with it.

 

i think ***us is right , the diagram doesn't look right to me either..they show the stop and tail lights as the same filiment in the bulb...the tail lights should be on their own,getting power from the lightswitch...TURN and BRAKE should be the same filiment....the black/grey wire coming from the brake switch to the turn signal has a wire connectiong the other two filments to together,and comming from the side of the brake switch that's hot when the pedal is depressed, that makes no sense, it defeats the purpose of the overide in the turn switch

 

There are extra lines in the diagram that have arrow heads on them that are not wires. both the flasher and the stop light circuit go into the selector and the selector switches to the proper side brake light filament. I don't know what those arrow heads are for but they confuse the issue.

 

i see that now , those aren't wires...but they still show the tail lights and brakes lights as the same filiment., so if you foget those two lines....and change where it says "stop and tail lights" to just tail lights , then it is correct and makes sense
