The red wires are the battery 12v+ supply for the switches to send through the blue and green wires to trigger the pumps up and down. The blue wires are wired on the "UP" solenoid but your gonna have to double check how the pumps are plumbed intot he system to see which wire will trigger UP/Down or IN/OUT. The purple wires are usually the trim limit senders on the drives to keep the pumps from pumping after the drives have hit their limits....

Yes 12 wires three from each pump, got the whole green blue thing and even understand the red wire to power the switches, but I don't know what to do with the purple wire at the switch term block.

Yes the purple wires are back at the pump for the drive limit, but also at the end of the harness up by the switch terminal block, why and what do I do with the purple wire?

How good are you at trimming your boat? I did not hook mine up I hate them. I do know when to stop trimming however so..... Neither my Formula or Donzi have the trim limits hooked up.

Change the plumbing if needed, but Blue should always be up for the drives & down for the tabs (it is the hi pressure side)

Not sure of the purple in your case, what you really need is the 3 wires from each pump - hot, up & down as shown on the attached. The hot will always go to the center terminal on the switches. The outer switches will have each terminal jumped to the closest 1 side off the double pole (6 terminal) switch in the middle.

How about making a drawing for us of the wiring on your switches to the terminal block?

At the end of the day all you need is 12 wires, might not hurt to unwrap that bundle and see where your 15 all go.

I have never seen the trim limit used on this type of panel, you would need a nother switch to bypass for trailer position.

Just took another look at your pump harness pictures, I am going to assume the purple is the hot wire on those. Why don't you power it up & jump the purple & blue and see what happens? Can't make too much of a fire if wrong

I thought you guys were good Multi meter and or test light are your friend!! LOL.

Magnum, Bam has it right you need the Blue to be up on drives and down on tabs so that you are working with the high preasure side of the pump on the hardest direction.

Another question; Looks like I need a fuse "a" I didn't figure on, is this usually a inline or at the fuse box? I try to stay away from inline fuses because you can never find them. I am out of room on my box at the dash.

Also I can use purple as red(hot) to switch? and I get the whole blue green up down thing, From what I read jumps are happening on the Pump side of the terminal block to put 15 wires on a 10 posts so everything works. I will find someone to help me use a multi meter to figure it all out I guess.

The easy way to remember what the solenoid wires on the drive trip pump!

Magnume: There is a fuse on the trim pump for the up and down. If you look close behind the bracket there is small black rubber case. That opens up for the fuse.

Magnum were you at?
