Hey all I'm getting my car finished up for a safety check and had some questions about hooking up the electric speedo.

What I have done:
Vss from 1987 v6 700r4 put into 84 trans where cable went
Changed gears for my rear end
Depinned purp and yellow wires from v6 harness and connected to trans

Now where in the c100 do the yellow and purple pins from the trans connector go? The yellow buffer in up In the dash already connected

All my gauges work except for speedo I'm truly stumped probably something simple I'm missing?
