[SOLVED] 36V 22A Controller wiring questions.

[Edward1]

I'm assembling my first E-Bike using a kit from a nearby eBay seller in Illinois US, I thought seemed reputable.
I'm waiting to hear back from him.

After doing much work on a mountain bike in preparation, and plugging things in, I find the connectors of the controller not matching all controls.
I can post a full image of controller wires if desired. The included manual doesn't exactly match my controller.

From the SW900 LCD instructions, it looks like the 2-Cond Brn/Wht plug is for (+) & (-) power for lighting.

Red Line (D+): Power Positive
Black Line (GND): Power Negative
Blue Line (DS): Controller’s electric door lock
Brown Line (DD+): Lighting control’s Positive ( If the controller’s software and hardware support the lighting control, do not need connect this line)
Green Line (RX): Receiving communication
Yellow Line (TX): Sending communication
White Line (GND): Lighting control’s Negative

Controller label:

The connectors that are confusing shown in this photo:

The SW900 LCD display, with extra 2-Pin unidentified connector:

I'm waiting on the power test until I get more details on the 3-Cond PAS input.
Any advice appreciated.

I find the connectors of the controller not matching all controls

That's normal for Ebike kits. They mix and match the options and parts all the time.

The connector meant for the PAS sensor is the one with the white wire. The connectors are the same but the wires are color coded.

To basically test the kit you need:

1) the on-off-display wires (LCD connector)
2) the motor wires (3 phase green yellow blue and the hall connector 5 wires)
3) the throttle wires (green black red in your pix)
4) power (battery)

Get those all hooked up correctly first, then post your remaining wires if you are still not sure.

3) the throttle wires (green black red in your pix)

I have two sets of green, black, red, one has a male connector, one with female connector.

I have the throttle control plugged into the female that mated with my male throttle control plug.
(Could this be a case of making both gender connectors available to match any throttle control?)

The red, white and black connector that you've identified as PAS is for the wheel-speed sensor:

The other red, white and black is for the throttle.
The green, red, black is for the PAS
The brown and white is probably for lights switched from the LCD, though probably only enough power for low power LED ones at battery voltage.
The red and black will be a spare battery voltage connector.

It's hard to say there are so many configurations available. Could definitely be throttle or PAS related.

Regarding the overall kit assembly: If you match the connector that fits, and if there is more than one fit, the actual wire colors match,
do you have any remaining ambiguity with hooking up your kit's connectors ?

Also, once you determine any connectors that will not actually be used, you can tape the ends up and tie strap them into a bunch so they don't cause further confusion.

All is working!

It looks like the second throttle green, black, red male connector was a throttle alternate.
The PAS operated perfect in with the matching white, red, black set from controller, per Etech.

The 22 Ga Blk/Red pair from the controller is my only unanswered question. It has no voltage on it at any time (off or on), its not the headlight output.

Hi Im trying to order this same conversion kit but I cannot figure out which connections are compatible on the battery I want to purchase. PLEASE HELP! Heres a picture of the different connections I can order the battery with. Can you please tell me which # is compatible? Thank you!

Totally a guess... But the red/black might be brake cut off connector?
