I picked up a 1978 cb400a that had been vandalized--all wiring connectors cut off, along with a lot of wires.

It is back together except for the ignition switch wires and the change relay, Honda 38320-41T-008.

If I read the wiring diagram correctly, on the change relay:

Brown/Red, Blue/Yellow, and Dark Green are to be on the three-blade connector.

Red/Brown and Black are to be on the two-blade connector.

But,
Which of the blades go to which color wires?
Where would I find those pinouts or a list?

Thanks.

Do you mean Light Green/Red and Black on the two pin connector? Hope so, otherwise got to check the accuracy of the schematics.
I'll check this when I get home.
Check to see if the pins on the change relay have markings. (BA, ST, P Si, E, 1, 2) If so, LG/R goes to ST, Bk goes to BA on the 2 pin connector.
1 goes to B/Y, 2 goes to Br/R, E goes to Green.
I'll verify this tonight. If it is the case, I'll update the FSM and schematics to include this information.

OK. I wired it up according to the service manual diagram.
I was a bit confused at one point:

"1 goes to B/Y"

According to the Honda service manual,
B is Black (not Bk), so B/Y is Black with Yellow.
I do not have a Black with Yellow.
But, I do have a Blue with Yellow, which would be L/Y.
Yes?
