Aft cabin lights not working

[zt260]

I dropped the boat back in on wednesday and unfortunately,the throttle only button was stuck in so i had to take the shifter apart,to get to the shifter the roof panel had to come out in the aft cabin and the reading lights had to come off,well we got the shifter sorted and put it all back together now none of the aft cabin lights work,i have checked all the fuses under the helm they seem ok,but looking at the wiring diagram it mentions Eplug 2 showing the aft cabin lights going to this plug,can any body tell me what this plug is and were it is,i have tried to attache the drg but cant sorry,my thoughts are leading to the earth wire (yellow) coming adrift as all the other lights work,any thoughts would be appreciated,

Sounds like the ground is not complete to me.

ps
I have the same problem with my throttle only button from time to time. Quicksilver 3000 throttle? Pop that button off using a knife and use WD40 on the inside a couple of times a years. Keeps it from sticking.

Just ordered the parts for throttle only button the small shaft with ball and spring keep sticking,

With regards to the lights when you look up at the shifter box on the inside of the hull their is the wiring loom on the loom their is 2 black wires running into 1 and 2 blue wires that i assume run into 1 but the 1 wire is missing these wires run to the aft cabin lights then on to the main loom i cannot find were the single blue wire has gone,i have a wiring diagram for this boat but it doesnt go into too much detail,i am thinking that i may have to put a new wire in as an easy option to create a circuit,what do you think?
i will try and get a picture next time im at the boat
