forgive me for asking, what functions are multiplexed? im asking bc when i disable the multiplex in kpro, the water temp wont work!! ive done a swap and had the engine harness cut / lengthened etc, this is a JDM dc5r btw. thanks

Water temp, charge light and A/C control.

yeah i was having that same question as well..but i also have another question...the 03 accord k24 has "can H(can communication signal high)" and "can L(can communication signal low)" when i was looking at the pinouts diagram of the ecu. is it the same thing as the multiplexor?

the accord also use "nc (countershaft speed sensor)". so is it neccessary?

The RSX multiplexer is incompatiable with the CAN bus found in the accord.

sorry for being a noob, but what does the "CAN" bus control?

theres several can lines on these cars.

B CAN (body)
F CAN (fuel system or pgmfi)
K CAN (dlc)
and some cars have other CAN lines such as UART or G-NET.

a CAN line is basicaly a communication line between control units or MICU's (multiplexers)

digital signals are transmitted back and forth on these lines. its the way all the control units talk to eachother.

this will be combined into one wire, can pls tell me what color is it or where can it be found. thanks

can i possibly run both stock accord ecu and ep3 kpro ecu at the same time? just like aem does with their 1030 model. can i just wire it off from the harness to new connectors to just control the "vss" and the can system so i would be able to control my a/c, gauges and what not? if thats possible, how would i about to do this..which wire (pinouts) are needed to do this? please help me out. thanks
