230 wiring diagram

[zenuff]

Does anyone have a wiring diagram for a 1967 230?
I would like to have the complete diagram. Also, how can the bulbs be replaced for the speedometer? It seems very difficult from looking at it under the dashboard.
Thanks for any info.

You can take the whole instrument cluster off from dash, get yourself under the dash and remove the electrical connector (the top one) secured by a small plate by removing the thumb wheel, and get your hand behind the instrument cluster area and feel the wing nut(sometimes it's hard to turn b/c of dirt and rust but hey, take it easy) and take that out, once the nut is removed, push the bolt stud so that the cluster will protrude from dash,but,you have to be very careful in pulling the cluster b/c you will break the tiny oil lines leading to oil pressure gauge. you can disconnect the oil lines leading to oil gauge by disconnecting it from the oil filter housing for easier removal. next, remove also the temperature sender from cylinder head but be carefull in removing that too, not to twist the lines as well.
