Switch Pad & EIM (Electronic Interface Module)

[OllieC]

Good Morning!

I am currently in the process of installing new electronics & would like to move some LED lighting to the Switch Pad location through the EIM. On the switch pad I have an ACCY location open as well a a Wiper location (no wipers) and they are fused at the EIM location behind the helm. I cannot find the location to attach the LED's to those switch points. I do have the wiring diagram, but am having a hard time figuring out where to look. Is this possible?
I know where the standard fuse panel is (below the EIM), but that is continuously hot and I don't want to add switches when I have a couple free on my pad. Here's a pic of the pad.

Thanks in advance. I'll be doing church stuff today with my family (Confirmation), and will check back later.

Considering the failure rate of that pesky eim box your best bet is to install a hardwired switch and fuse/breaker

I Connected a friends ACCY1 switch to an external GPS. I found the wire stubbed out a few inches from the EIM mounted to the stbd side of the helm behind the plastic POS cubby. If you download the manual for your boat you'll find the schematics in the back and a number identifying the wire you need to connect to. The EIMs have fixed circuit breakers (current values are on the schematic) so make sure you LEDs are compatible.

As for using the wiper circuit, the wire is probably ran in a harness but you should still be able to figure out which on it is coming out of the EIM by wire number or pin # on EIM.

The second EIM is usually in the engine compartment which might be easier to get your LEDs connected to. ACCY2 is located there.

I did this a few years ago - so my memory might be a little fuzzy.

Thanks insfnds.

I will have to dig into the rats nest of wires more deeply. I guess that would be a good time to better organize them. I 'sort of' assumed those connections would be in the bundle, but was hoping for an easier connection like the buss bar below it.

Look at your electrical diagram. There will be a pin labeled on the EIM for the output of those circuits. You may need to have a Deutsch socket crimped to the end of a piece of wire, remove the hole plug and insert the wire. Be sure not to exceed the amperage rating of the circuit, also noted on the diagram. Also size your wire to the device using ABYC tables. There should be a ground block in the area for the negative wire. Use proper stranded marine grade wire.

Thank you IMG. I have cleaned up some of the wiring and will probably dig more deeply into this, this weekend. All I will be powering are decorative LED lights for speakers gunnels and cupholders. The fuses for the unused EIM locations (water or hose down pump, wiper & accessories) are actually fused pretty large for my application. If I had a surge, the LED's would probably fry before the fuse blew.

I'd like to utilize 2 switches, one for the helm, (speakers & cup holder) and one for the rear (gunnels) because if I am cruising at night, the helm LED's are too bright.
