Magnum were you at?

Thats what I thought, the fuses on the pumps protect the whole circuit and I don't need to protect the switches to the fuse box. They are protected by the fuses at the pumps right?

My question is still the same, how do I end up with 15 wires on 10 posts with a total of 12 wires on the pump side of the terminal block???
Please look at my post 1 pic 1 and you can see the old terminal block has 15 wires on the pump side. I have never gotten the answer on how to wire the pump side of the terminal block and I would like to do it this Saturday. I know somebody knows, don't hold back guys.

Yes the fuse at the pump is all you need.

Do you want to wire it exactly as it was? Are you going to put the trim limit switch back in?

I could help you better in person probably.... :(
The extra wires on the pump side do a few possible things....

1) If you have a trailer button, these wires most likely bypass your trim limit switch (if you have one).
2) The wires on the block control both drives at the same time. Three switches on the dash... Port, Stbd. and Both.
3. A lot of trim switch systems have a one way diode between the two switches and the one that controls both of them.

Is that what you're asking?

I have a think I would have a limit, my drives are Bravo sounds like I need that.
Yes, I want to wire it exactly as it was, I have no trailer bypass button just the switch panel in the pic and no diodes either.
Just need to figure out how to wire the pump side of the terminal block like they had, but I have 12 wires coming up from the 4 pumps and they had 15 wires on 10 posts.

Best I can tell you do not want to hook up the trim limit switch because if you do you will not be able to trim up your drive for trailering. Then you have 10 wires coming from yout switch panel to the terminal block. Then you have 12 wires going out to the trim pumps the powers according to your notaion gets put together. I am not a big fan of that putting the power together because you are effectivly giving your trim pumps 40 amps of protection instead of 20. I would get another terminal strip with 12 connectors on it and that way you have them all fused properly. Plus if the fuse blows you do not loose two pumps.

Lets try to keep it simple, can we figure out only Green.

I have 4 green wires from the pumps;
2 Green Down for Port+Starbord Tabs.
2 Green Down for Port+Starbord Drives.

The right side of Terminal Strip has 6 green wires vs. my 4.

Can anyone tell me how to take 4 wires from the pumps and get 6 conected to the terminal strip.

Terminal 10 AT TOP with 2 wires is starbord and both Tabs.
Terminal 8 with 2 wires is starbord and both Drives.

Terminnal 2 with 1 wire is Port Drive
Terminal 3 with 1 wire is Port Tab

All that is 6 wires I only have 4 even a jump wire dosn't seem to add up to 4 terminals with 2 greens each and 2 terminals with 1 green each?

the extra green and blue wires should be connected to the switch that's marked "Both", when that switch is fired up it activates both the drives at the same time. You can jump the wires at the buss, where it looks like it was done, or you can jump them behind the switches.

same for the tabs.

They apeared to be jumped at the switch as I am looking at it that is what it looks like to me.

Magnum you have to read my post above. Do you want this STOCK or CORRECT?

The wires appear to be cut so maybe it was wired from the bus at one point and now it's jumped at the switch.
