Installing ALP quad system on my motorcycle. CPU must be placeed under the rear passenger seat. Would like to place the LED in the instrument cluster. LED won't reach. Any recommendations on how to extend the LED cable would be appreciated. Also, this is a Gen 1 CPU, if I program the settings to have the LED remain dim, at say level 3, will the LED stay illuminated blue but, at the dim level after the start up sequence?
External LED can not be dimmed on first generation CPU's. If you need to extend it you can try to find a coupler and a short additional cable.
The cable that is used for the LED appears to be RJ22 also know as RJ9 or, RJ10. There is actually no official designation for it, hence it goes buy a couple of different designations depending on the vendor. This type of cable is 4P4C and uses the standard 4 pin modular connector which is used to connect phone handsets to the base unit. NOT the RJ11 cable and connector which is used to connect the base unit to the wall. Also, and VERY important for this application you can not use a standard hand set RJ22 cable to extend your ALP LED RJ22 cable. This is because phone RJ22 reverses the pin order from one end of the cable to the other. So, for example at one end, black is pin 1, but at the other yellow is pin 1. For data transmission and I believe for this application, you want a cable which is, "straight through," or, "pin 1 to pin 1." The color wires in the 4 pin RJ22 are, starting from pin 1: black, green, red, yellow. I am going to use a 3 ft RJ22 pin 1 to pin 1 cable with a RJ22 female to female coupler. The standard ALP LED cable is approximately 58" long. Add 36" for the extension plus 1" for the coupler. That brings the combined length to 95" or, 7.97 ft. My two questions that maybe you could answer Tom: 1) Am I correct, that the ALP LED uses RJ22 straight through, pin1 to pin 1 cable and, 2) will there be enough voltage to overcome the additional resistance associated with the longer cable length?

Spoke to Eddie, it is in fact RJ22 and it is straight through, pin 1 to pin1. The length should be ok. One other note, if you're not going to cut and crimp but, use a female to female connector, the connector should also be, "straight through." Hope this info helps anyone else that might need to extend their ALP LED.Quote:

A link to the parts would be great

I extend mine by cutting the original cable at any lenght , then joint\solder any 2 wires cables at both end. Finalise the joints with shrink tube.
I used telephone cables ...any cables will do , even super thin wires.
In your case , a motorcycle , i would prefer the cutting\soldering than using connectors due to long term corrosion problems , unless you seal well the connectors.

Here are the links to what I ordered. I have not yet received these items so I can't yet say they will work for sure, but they should. When you order the RJ22 cables make sure you select "Data, pin 1 to pin 1," not Voice. You can also select the length which luckily can be had as little as 3ft.Quote:

Do you (or anyone reading this) see any problem extending Beltronics STiR plus cables this way?
Hmmm, not sure. I would be concerned with the level of resistance when the cable gets that long. If you take 3 six foot sections of RJ11, string them together and try to power a Valentine One, it wont work. Two 6 ft sections linked together, no problem. According to my buddy who is a master installer, lengthening the RJ22 LED cable with an extra 36" is not a problem. I guess an LED doesn't require much voltage to operate.Quote:
