I have a 1976 ford with a 5th wheel tailgate.

I want to add 3 lights for each side of the tailgate for turn signals. I want the lights to flash in sequence from the center of the tailgate out.

I had thought about getting a longer time delay main relay for under the dash, but then I'm confused about how to wire it in the back.

I would like to think that I am somewhat knowledgeable about a setup like this, I guess I'm just getting "brain freeze" on this one.

Thanks for your help in advance.

Here's the circuit:

Note that VDD and GND for the ICs are not shown in the circuit drawing.

Pin-outs:
(7)555		4017
1	GND	1	Q5	9	Q8
2	TRIGGER	2	Q1	10	Q4
3	OUTPUT	3	Q0	11	Q9
4	RESET	4	Q2	12	CO
5	CONTROL VOLTAGE	5	Q6	13	NOT ENABLE
6	THRESHOLD	6	Q7	14	CLK
7	DISCHARGE	7	Q3	15	RESET
8	VDD	8	GND	16	VDD

interface output with relays and use 3 of the output for what u want!!!
