Dose anyone know where the cruise control ECU is on the bike have a gl1500 se 1993
Only 93 and later, at least for US models.the Cruise Control works off of Engine RPM on the 1500s.
"Beginning in 1993, all GL1500 rocker arms pivoted on needle bearings, and the cruise control was updated to directly read crankshaft speed for enhanced precision."
Just as an aside, while acknowledging the accuracy of your statement, when I got my new to me 1500 the cruise control wasn't working. I went through the troubleshooting protocol by checking the pins at the cruise control. All checked out ok and it turned out that the circuit board on the cruise unit was cracked. I managed to solder jumpers across all the circuit breaks and also reinforce the board and it has worked since. Meanwhile I bought a replacement just in case. The info regarding speed limits is good - thanksUnder the trunk. They are pretty robust, most issues can be traced to the myriad of switches and sensors going to it.
What seems to be the problem?
