I am installing a door popper in my 1980 Plymouth Arrow (same as a Dodge D50) I noticed in the instructions they have two diodes inline with the parking light flash circuit. I am assuming it is to prevent the circuit from being energized when the lights are turned on. I have two questions here first do I really need 2 diodes or can I just put one in the supply line coming off the brain box and two there are no diodes included, nor is there any reference as to what diode I need to run. Any help here would be great!

I forgot here is the link to their instructions https://files.thehoffmangroup.com/instructions/PPP35K_KL800v2.pdf

It looks like they are using it to isolate the left and right parking lights. Some cars have independent circuits for each light. If you do plan to use diodes, I suggest 6A1 rectifier diodes for parking lights.

If both of them are coming off a single wire then separating then why would they need to be isolated? You don't think it is there to prevent the brain box of the door poppers from becoming energized when the parking lights are turned on?

Sorry, let me try to clarify since I was being general with my response.
If the parking lights are on the same circuit than diodes are not required. If they are independent than you will need to diode isolate them. Your car does not have independent parking lights, so you do not need the diodes. As for backfeeding from the parking lights, it will not happen since the relay isolates the lights from the brain. Hope this clears it up.

Ahh, that is true kind of forgot about the relay in there, so the relay is grounding back through the brain box correct?

I guess you can say that.
