tried putting a sequential in 85 fiero. Added a third turn/brake socket in center. Can get the 2 outer lamps to work. When I add a third in the wiring all lamps flash together. Any ideas of what is wrong ? Thanks Ed

Are you using the relay method or the 555 timer? What schematic are you following? Sounds like you have a simple wiring issue....

A while back there was a guy on this forum by the name of Lawrence Mazza who runs a company called web electric. He sold all kinds of control modules including a sequential turn signal board.
The company is still in business. If all else fails you can find this product here:

It is a Web electric setup Ask him and he said post here

It appears to be a step by step process of syncing the new system.

Testing Procedures for Sequential Turn Signals

After installing your WebElectric sequencers, BEFORE you put the car back together, perform the following procedure:

- Make sure the car's engine and all lights have been off for at least 5 minutes.

- Start the car and let it run. It is important for the electrical system to be fully energized in order for the electronics in the sequencers to sync properly.

- Turn on the left signal and let it run for 1 minute.

- Turn on the right signal and let it run for 1 minute.

- Turn off all signals and stop the engine. Allow the car to rest for 5 minutes. (Now's a good time to get yourself a beer).

- Start the car again and test the signals. If the lamps are not sequencing, or are sequencing very, very fast, or one or more of the lamps are not coming on, double check your installation.
