separating the brake lights from the turn signals 91 f250

1 Attachment(s)

This will work on other vehicles as well if you want to add separate brake lights to your vehicle, but the reason I had to do it was because the steering column I installed in my 91 F250 came out of a 93-ford ranger and did not have the wire to the turn signal switch for the brake lights it only had 6 wires and the 91 required 7 wires to be able to connect the stop light switch to it
What I did was I used a pair of relays since I did not have a single relay with double poles I wired the hot side of both coils and the hot side of the relays all together these 4 wires would connect to the stop light switch next I grounded the other coil terminals I then wired the #30 or the nortmally open terminals 1 to the left rear and one to the right rear

Love the soldering iron.

If you are considering mounting something like this in circuit and plan on paralleling it into the existing 2 rear turn/ brake light wires you may need a pair of blocking diodes to prevent back feed from the stoplight switch to the turn signal switch otherwise on some vehicles it may cancel out your front turn signals when applying the brakes
