Rear Red Turnsignals Double as Brakes, Increase Brake Lights with Rear Turnsignals Options

[Spoke]

Engelbert designed a solution for the 911 to allow the rear turnsignal to double as brake lights for a larger brake footprint. I believe he is planning to market it for the 911 guys. Because of the layout of the 911 rear light housing, to install the module in the housing, the housing has to be removed and opened up.

I thought this would work well for the 914 and should be easy to install as access to the rear housing and wires is in the trunk. Engelbert was ok with me basically copying his solution.

Here's a link to his 911 solution:

rothaus (Engelbert) 911 RTS to Brakes

The RTS-Brake module would reside below each rear light housing. One for each side. Here's the module being tested on the bench.

The module has 6 wires. Brake-in, Brake-out, RTS-in, RTS-out, and 2 grounds. The wires have QC connectors and go between the OEM wiring and the light housings.



The IN wires have male connectors and the OUT wires have female connectors.



On each side, pull the brake, RTS, and GND wires from the housing. The wires connect to the IN wires and the OUT wires goes to the housing.

On my '71, the RTS QC connectors don't have insulation so a short piece of heat shrink provides the insulation.



Once the RTS connectors are insulated, pull one wire at a time and install.





Here are the modules in action on my 914. My 914 is set up to always have the running lights on with the ignition.

I built an extra set if someone would like to try them out. If folks are interested, I'll be selling these for $45/pair.

Here's a connection diagram for these RTS-Brake modules. Connecting these modules is straightforward. Pull one wire at a time and plug the OEM wire into the corresponding module wire color and wire color to the housing.



All the connection information and OEM wire colors were used from Jeff Bowlsby's diagram:
