Hi,
I have an 86 SE 2.8, a ferari replica, I have replaced the gauges cluster with SPEEDHUT indipendent gauges with Pisa wiring harness to bridge, I need to use the speedometer board, see image below, as the amplifier, so I need to solder the wires (YEL & PPL/WHT) that are coming from the VSS to that board and get one wire with amplified signal to go to the speedometer, could you please tell me where are the points to solder? I belive that the original speedometer gets his buffered signal via the 4 bolts attaching him to the board. how can I get one wire from that?
