Sequential turn signal issue

CobraRGuy · May 10, 2025

Hi everyone,

I purchased a set of '96 3-lens turn signals so I could implement sequential turn signals (I think they're way cool). I was fortunate to find a set in white in perfect condition. I then found a sequential wiring harness for SN95s. Everything wired up fine, but the signals flash way too fast. What I need is an adjustable relay. Unfortunately all of the 5-pin adjustable relays I've found are designed to use with LED bulbs. All of the regular ones I've found are 3-pin, which I don't believe will work.
I am not familiar with using LED bulbs in turn signals. I wouldn't mind buying LED bulbs, but I don't know if they'll work with the sequential wiring logic. At this point I'll probably just buy LED bulbs and an LED 5-pin adjustable relay and see if it works.

Here are my questions:
1) Does anyone know if a 3-pin relay will work?
2) Has anyone used a sequential wiring harness with LED bulbs?
3) Is anyone aware of a 5-pin adjustable relay that is designed to work with incandescent bulbs?

Thanks, CobraRGuy

I believe raxiom sells an adjustable relay. Another route you can take is to replace the resistor in the relay to slow down the turn signals, if you’re handy with a soldering iron.

Thank you. They don't sell an adjustable one, but they do sell a 5-pin that's got timing set up for incandescent bulbs. They also have the same for LED bulbs. I ordered one of the ones for incandescent (they're not expensive). If I don't like it I'll buy one of the 5-pin adjustable LED relays and replace my incandescent bulbs.
I'll report back with how it went, but it will be a while since I'm still deep into the Holley HP EFI conversion.

I thought it was a capacitor that needed to be replaced not a resistor but I could be wrong. I say this because I swapped out the cap in mine to adjust the timing and it wasn't all that hard if you know how to solder. The top of the flasher is held on by tension clips you can pop off/on and the cap is right there IIRC.

Years ago I read a thread where the op put another resistor inline with one on the board but of course I can’t find the thread after all these years. But I did find a video where the guy puts a second capacitor inline with the stock one and it slows down the flash as well so either will work.
