Single Cam to dual cam swap

[Wazawai]

I just did a Full engine/Tranny swap on my 240. I went from '89 KA24e w/ automatic tranny to '91 KA24de with Manual tranny. My buddy figured that we would have to cut and color match the wires to my ecu like he did for his SR swap, but now my tach and my spedo dont work. I think the single cam tach is electronically different from the dual cam but for the speedo, and reverse lights? does anyone have any experience with this?

There were about 7 green wires that didnt match on the chassis side. everything else is working fine tho. engine turns over nicely and the tranny shifts smooth...

This is my first KAe-Kade swap so I could use some serious help on this.
