Reassembly: 454 Mag Mpi
 

Hi all,

I am reassembling my 454 mag mpi injector/efi wiring. I have the manual 23 with the schematics, but was wondering if anyone has or could take me a few pics of theirs for reference. I left the harness with the injector plugs on the intake purposely when it went to the machine shop. It came back in a box next to it. Never had a chance to take any reference pics. Any help would be greatly appreciated.

I have a 1998 454 MPI (385 hp) that I am rebuilding. I took lots of pics during disasembly - I might be able to post those on Snapfish or something similar. Let me know if its the same motor as yours.

Yep, same engine as mine. If you could email, I'll post my adress.

Tebo do yourself a favor and throw away the oil cooler and lines.. Buy new. I know 3 people including myself that reused the old ones and lost a main bearing. Not worth it to risk it.

wow, I'm going thru the same process right now and just can't figure out the wiring harness routing. It would be great to have some pics!

Would any pic's still be available to help identify the wiring harness connector to injector order for a 454 mag / mpi?

Thanks

Here is one from the top. The 2 per cylinder is pretty obvious when you get the wiring harness routed, but not sure how to tell which of the 2 go to each injector. If you notice the white tape on the front wire for each pair, I have them labeled.

WOW !

Can't thank you enough for your help. I have been very careful during the tear down, labeling, numbering, etc...

Get another person involved and the practice goes by the wayside.

Thanks again ...

28 Elim's photo is a god send ...

There is an observation I made, the wires that are exposed between the injector plug and cable wrap are different colors. It looks like they are red / blue on some and red / green on others. Haven't quite developed a pattern, yet.

I'm feeling much better about "reconstructing" the proper connecter sequence.

I'm open and thankful for ant other input.
