Hey guys, I left my truck out by a tree for a month, and it wouldn't start. Turns out the engine compartment was fill with junk, and packrats had chewed through vacuum lines, injector wires (and more) and plug wires.

I can figure out the plug wires, but want someone to verify where the wires along the fuel rail are going. I've put up 3 pictures with colors showing where I think these are supposed to go. Could someone please take a look and verify? I've tried to color code the wires. Also want to make sure the green and white vacuum lines don't branch off from where I think they go. The one sensor that lost it's wires has the same colors as the fuel injectors so it's important I get this correct. I've seen pictures where the two wiress branching off from the middle of the wires BOTH go to the injectors, if true, Where do I connect the TAB (or TAB?)

Thanks
Pete

ABOVE: Black arrow points to sensor. Maybe MAF sensor? Most importantly I want to be sure those wires at end of fuel rail go to this sensor. White wire has black stripe


Above: Yellow should have been white. Pretty sure these are correct, but want an expert to verify. I don't have a good picture of my original engine Vacuum lines are just reconnected without branching.. Right?


Here again is a blurry pic of the sensor with wires dangling. White wire has a black stripe. I think they connect to the end of the wire bundle along the fuel rail.
I'll be outside but will have my phone with me for updates! Thanks again!

I was naive to think the stupid rats hadn't gotten under the plenum. I have plenty more work ahead of me than I thought.

So new vacuum lines and some other updates are in order.

The vacuum lines are shown on the vacuum map on the VECI label on the hood above the master cylinder, but they're all virtually identical:

On the truck I'm building now, I'm using silicone tubing to replace the vacuum lines:

To correctly re-attach the wires, you have to know what you're attaching them to. If your truck has a MAF, it's on the air filter cover outlet; not the engine. Study this & the NEXT several pics, and their captions:

If you don't have a Haynes, now's the time to get one:

In the meantime, you can look up most of the wiring diagrams here:

You don't have to use your real e-mail, but you do have to switch to WIRING DIAGRAMS.

If you take your time, and peel back the harness wrap to expose the wires' original colors (not age-faded), you should be able to put them all back together. But you might have to replace some of the pigtail connectors, if the wires are chewed off too short. I've done many repairs like this:

If the mice aren't still in the truck, they'll come back. Either BEFORE you start taking it apart, OR after you finish putting everything back together, WASH it thoroughly to remove as much food & bedding material as you can.

Dig the trash out of the cowl drains, and remove all the mud/grass from the frame & suspension.

Buy a bag of rat poison, and spread it on, in, & around the truck. Something like these:




What is that hack with the bluish tape at the top of your 2nd pic zip-tied to the brake booster hose?

Thanks for the pics and links. I've cleaned up the engine compartment and blew everything out of the crevices. These things like rocks! I was pulling rocks out of everywhere. I killed the rodents with traps, but will check the frame.
