NiiChan GT-R Posted January 27, 2012 Share #1 Posted January 27, 2012 ...Does anyone have a diagram of these mapped out, as to which terminal does what?I'm talking about the two big plastic plugs by the transmission tunnel/firewall in the passenger's footwell. I don't even know how to begin searching for them or what they're really called... Each has two rows of about five pins each, I can provide a pic if needed.My temp. and oil pressure gauges quit working, someone told me to check these connectors and clean them out with contact cleaner and a brush... Well, one of the connectors was pristine, the other more or less is disintegrated. So I'm wondering if anyone can direct me to what the function of each of the plugs is, so I can figure out what's affected by the broken/corroded pins.Does anyone sell a sufficient replacement connector?Thanks, oh yeah, car is 75 280z.

beermanpete Posted January 27, 2012 Share #2 Posted January 27, 2012 The body electrical section of the service manual has the pin-out for each connector. Go to http://www.xenons30.com/reference.html to get a copy of the manual of you do not already have it. Link to comment Share on other sites More sharing options...
NiiChan GT-R Posted January 27, 2012 Author Share #3 Posted January 27, 2012 (edited) Thanks... From glancing offhand behind my desk at work, thumbing through the PDF on my phone, it looks like it ought to be either connector C5 or C6 per the manual that I'll be dealing with, I should be able to confirm that once I check the car again. From there, I suppose I'll be trying to find a way to replace or route around the plug. ...Everything else on the car that's electrical still does work, all interior lights, rear defroster, audio etc.... Everything but for those two gauges, and an intermittent seatbelt buzzer. So hopefully I will find correlation among the pins and those Edited January 27, 2012 by NiiChan GT-R Link to comment Share on other sites More sharing options...
grantf Posted January 27, 2012 Share #4 Posted January 27, 2012 In the past I have routed around the bad connector pins. Now I am in favor of repairing the plugs. It is possible. Search for molex connector pins. Link to comment Share on other sites More sharing options...

SteveJ Posted January 27, 2012 Share #6 Posted January 27, 2012 Vintage Connections is an excellent source for a lot of our connectors. However, I don't think he carries molex connectors. Link to comment Share on other sites More sharing options...
