Wiring in Engine Bay Questions ..
My fire wall electrical block is missing a wire ,,and I think it is the Oil Preasure Guage wire..blue one
If it is,, I will crimp a clip to a 20 ga wire and plug it in to this spot..Any body know if where I have shown it in the drawing , is correct? Also ,,I find that the white wire is no longer needed ,,just take wire out of the plug and toss it ? Is this wire of any use for anything else..? One more question is :: where are you running the wire to the distributor at through the fire wall at.. ? First and second is a picture (not mine ,borrowed)showing the electrical block I am talking about . ![]() ![]() ![]()

Re: Wiring in Engine Bay Questions ..
Depending on what equipment the truck came with it may not have a wire in every slot/hole.
The oil pressure gauge is mechanical in these trucks and has a tube going to the back of the engine if it is a V8. That's a nice diagram Sport/Truck many of us will be saving a copy of that in our documents files or bookmarking the link, thanks. |

See my thread in the electrical section about adding extra wires into the bulkhead connector.

Re: Wiring in Engine Bay Questions ..
nice, I'll have to print that out and laminate it..
may even have it made into a decal and stick it under the hood.. so with hood open you can read it.. |

So I went to National and they cant even find them in thier books and O'rileys/Shucks do not have them either.. I guess I will try the wrecking yard and get the whole block and maybe clean up some old ones.. It's hard to find someone who really knows what these clips look like and how to work with them and your pictures are the best . I also could not fine purple 12 ga wire anywhere ,,except for Home depot and I would have to buy a spool for $60 to get it.. I am not giving up ,,just running out of places to go find these hard to find things.. thank you for all your help ,,appreciate it ..GP

You should consider a new harness from M&H, they use the original drawings and colors & connectors. Plus you can have them update your harness to include electric choke, internal regulated alt. Headlight relays. etc. Your welcome, Thank you.

My local (next door to where I work) NAPA store ordered the box from the warehouse and sold me the pieces individually. If you want me to pick some up for you, I can walk over and see if they still have any. |

I used the 6 digit numbers and it found both male and female terminals ,,It does say that I cannot order them online and would have to get them from my local store.. I kinda want them tomorrow if I can get them .. As I said ,,the local Napa store person said none to be found in the area .. so I will go to a wrecking yard tomorrow and maybe buy the both both parts and then take it apart and find me a terminal and just rehook it to my wire and then solder it .. If I run out of options then I would be glad to check back with you on you getting me some ..thx for all your help.. gp

Re: Wiring in Engine Bay Questions ..
What kind of grease is used to protect the connectors in the firewall bulk head from the elements ..I read in one of the postings that do not clean this grease off when taking apart .. Mine has been wiped clean of any protective "anything" it ever had..
