Step 2Removing the RA stopDEC motor wires
This step, as far as some other tweaking to the telescope, which you can perform along the way, are perfectly covered by Bob here in "My DEC cord mod" section. The wiring diagrams and connectors pinouts was taken from this site, and this site (The LX90 PCB layout is very close to the ETX125's except the voltage of ETX is 12V vs. 15V for LX). And/or retrieved in place by a multimeter.
I have nothing to add to this step (which is actually the most thrilling part of the procedure), except that in my case I've decided to use the 8 pin retractable network cable and the RJ45 jacks instead of RJ14's to connect the base to the right fork arm. Also the hot glue works here as well as the epoxy. Everything else was done by exactly following Bob's excellent instructions. The other 4 connectors of the RJ45 was used to route the Aux port signals (Clock, Data) and RS232 port signals (Rx and Tx).
This is the straight retractable network cable, which I bought off eBay for $1. It's very light weight, and retracts/extends automatically in response to the scope's RA movement:
