which main harness do i need?

Hello fellow enthusiasts,

I own a '77 kz1000a1 bitza. When purchased, it came with a kaw 900 that was in many pieces, but without wiring.

The kz1000 now requires main loom replacing. Loom is finally beyond repair after a few PO's

I am of the belief that the current main harness & handle bar contols have been donered from the kaw 900, due to the LHS (hi/lo beam, turn signal, horn - no pass tab) control block being terminated in a single 6 pin connector which fits neatly into the corresponding 6 pin connector on the current harness.

Unfortunately, the RHS control block has been soldered directly into the main harness.

From what i can determine from schematics and pics, the z1000's control blocks mainly had "flying/single lead" terminations, as opposed to a "6 pin connector"

Given the following constraints, could anyone recommend a suitable main harness (im thinking the kz900 could work)

I would like to reuse or replace the LHS control block terminated with 6 pin connnector.

I would replace the RHS control block (flat top) from a kz900? terminated with 4? or 6? pin. (could anyone confirm number of pins?)

The warning instument cluster is original z1000a1 i.e "left & right turn signal indicators" as opposed to z1 "turn signal indicator" (is the wiring

different in the 9 pin connector?)

The current ignition switch has a 6 pin connector with 6 wires. I don't mind if "park" lights are still not usable.

The reg/rec is modern 5 wire style.

I do not have hazard light controls or associated wiring.

Here's the clips on mine. Used a KZ900 loom for my Z1 instruments. Rats nest wiring.

wow, that was some spaghetti junction you managed to unclusterfork there Nice work.

I would prefer the ease of disconnecting one main lead (kz900) from each control block rather than having to disconnect all the discrete leads (Z1000) from each control block, so I am hoping the kz900 loom will do the job.

i think this is the difference between the kz900 & the kz1000

It's up to you.

Thanks Steve, for putting that video out there.
It has answered a lot of questions about the differences between kz900/1000 harnesses.
I think i actually have a earlier z1 loom because bike has only 1 * 20A fuse, and no wires coming from loom for the other (absent, in my case) 2 * 10A fuses
I'm gonna replace my loom with kz900 and also get the 3 fuse holder because at least my LHS block control will fit it correctly.
You have helped tremendously
