300 CE oil gauge
 

I had to remove an instrument cluster out of my 1988 300 CE to replace dash board light dimmer. When I was trying to put everything back together i've noticed that i have nowhere to connect oil pressure red wire. I have about 5" long red wire which sticks out of this cluster. End of this wire looks like it was soldered to something. I was looking everywhere inside dash board and couldn't find enething to coonect this wire to. Please help..... Mike
