I have a 99 Boxster base. Bought a 4-stalk from a forum member and bought a wiring harness from Dwight. 
1st question I have the OLD guage cluster, black, white and blue plugs.  Based on what I have seen the obc harness connects to the white plug. is this correct? 
2nd question does anyone have or can give me a layout of the plug and where the 4 harness wires should be input to the back of the plug. the problem is the plug has each port numbered but at 55 even with glasses and a magnifying glass I cannot "see" the numbers. 
sucks getting old!
