When I get these trucks and their problems, sometimes it is just best after diagnostics to see if they start and confirm that the ECM is the problem. I am just saying that if you can start the truck that is 3/4 the battle. I like to know my possibilities to make that happen. Running well is...

Thank you for the reply. So according to the numbers I have a 3126B which apparently I will need a tune on the computer but since you said, if it even drives which I doubt, you know of course what I need to do and that is to see if it moves. And if it does it will mean does it move enough to...

This is how it is so far. Cat 3126 Engine #7JZ06815 is replaced by Cat C7 Engine #7JZ00594 Swap Mechanically went well Reporting back that though I haven't driven down the road which I am going to, it started using the 3126 ECM. When I finish, I will report back as to how well it runs.

So all the items I was looking for were on page 12. My schematics are printed on 8.5 X 11 paper and is very small. Is there a larger copy available or do I need to look for a print shop that can copy these on 14 X 20/ Needless to say thank you for your assistance!!! BTW page 2 is unreadable is...

Thanks guys. Going to have to study this. Maybe I need to go back to Schematic Reading 101? Is there a legend on all the initials?

Let you know. Thank you for the response

TL number is a 4 gauge andcapable of reaching the alternator. I will go to the schematic again. I do have to say the schematic for the A0 are alot nicer and easy to follow than the A1's. My opinion for what that is worth. LOL I think I just figured it out, hand over hand to find the other end?

TL 508 229A 229B 3000 Changed an engine on this truck and due to circumstances lost track of where they go and whether they are 12 or 24vdc, or negative or positive. I have gone through the materials I have and have not found a listing for wire numbers. If it is in the Tech Manuals I don't know...

It's a thought! If you decide to do that it would be a wonderful thing if you reported back.

Does it harm anything to try???

Don't know if I need to post to another title? If I do I will Engine is installed but I have not attempted to start because I am having difficulties with wiring and previous repairs that have been done. So in order to clean up and be sure of correct locations for the connections, I do happen to...

Son of a gun, At your prompting sir I went to wikipedia and learned about the 7.2 Litre Cat engine. I did not realize that they changed the name of the 3126 to C7. But in 2003 to comply with EPA they gave it the new name. Hats off to you once again sir. I really didn't know how to look that one...

I don't know where to look so I know the experienced here can help me out, please. I had an earlier post about motor oil in coolant system and it wasn't oil cooler, so I proved what it was. Needless to say the engine needs replacing. I have a crated drop in from the Military and it doesn't have...

I like my Light Switches a little on the "wonky side" LOL Thanks again.

Didn't know that and thank you for the reply!!! So then is it better to go back to the mechanical than the pushbutton? Even as far as cost and dependability. Application is fire service

I'm new to these switches. If you are attempting to tell me there are replacement switches which are better, please say. I haven't heard of any catching fire so please be straight forward. Thank you really!

I will check that out! Thank you

You can open them up? Good to know. Anything special going to jump out or all self explanitory?

If that doesn't work does it mean it broken or is it on a module?

I take it you have I take it you have Locker Diffs and if so can you point me in the direction of type and cost? If not , can you say what Diffs you have in it please and thank you
