Easy fix to the stock system

Using ChatGPT as my car-sultant, it was relatively easy figure out what was broken in my original sequential tail light system. This part resolved the problem with the emergency relays that were rust filled from water leaks in the trunk. Removal/replacement was plug-n-play.

Easy fix for anyone who still has there older seqential motor and directional relay set-up. I didn't use this on my car but gave it to my brother to use on his "68 XR-7 and it fixed his flasher problem.

Works Great and Easy Installation

I got the emergency flasher in and immediately went to install it. After 5 minutes, I had sequencing tail lights again. It may not look exactly right, but it is under the filler panel and trunk mat anyway.
