Almost done here. Rather than starting a new thread with these new questions, I'm editing this first post with new information so you don't have to read through the entire thread. Thanks again in advance. You've all been very helpful!!!

Info about car that should help with Pic #6: The distributor was converted from points to the electronic points and now has an MSD ready-to-run billet with Blaster 2 coil. The positive side of the MSD coil is currently receiving power from the IGN lug on the fuse block, not from the engine harness. I didn't set it up this way in case anyone was wondering. I'm not Bubba, I'm trying to remove Bubba from my car.

Pic #6
Both of these wires went to my coil at one time. I currently have 3 more wires that are currently connected to the coil for a total of 5 wires. Trying to figure out which to use now.
Wire 1 - the yellow wire on the left comes from the solenoid and per my wiring diagram is supposed to hook up to the negative side of coil. My MSD instructions show only the distributor wire being hooked up to the coil's negative side.
Wire 2 - the green wire on the right with all the tape on the end goes to the engine harness and has 12v power only when the ignition is on. I'm thinking this was original ignition wire.
Wire 3 & 4 (not shown) - positive and negative from MSD distributor. These are currently hooked up to the coil.
Wire 5 (not shown) - positive side of coil to IGN on front of fuse block. Currently hooked up.

My thoughts is I obviously keep the MSD wires, pull out the wire from the IGN altogether, hook up the green wire to the positive side of the coil per MSD's instructions, not my Corvette manual. But I don't know what to do with the yellow wire. Delete that too?


Pic #7
Removed all the tape and discovered this is the 10 gauge red wire that routes from the battery cable lug on the starter solenoid, hits one of these tubular type 'capacitors' you can see, then about 4 inches of bare wire (no insulation whatsoever), hits another 'capacitor', has insulation again, then gets up to the middle of the firewall and splits to the same 10 gauge wire plus a 14 gauge brown wire, and they both go to the engine harness. My question here is between the two 'capacitors'. Is that supposed to be bare wire? Can I replace the wire from the solenoid to the split off? If so, where do I find a wire with these inline 'capacitors'?

 

#5 looks like it's to the TCS solenoid on the intake manifold
#4 looks like the TCS jumper connector for the temp switch on the passenger head
#3 is the wiper door limit switch and the wiper plug is what's MIA - the plug probably melted and he simply shrunk on spade terminals. Also that "ground wire" on the left side of the pic doesn't belong there. There should be a black ground that runs from the starter bolt up to the blower motor then across the top of the firewall for the wiper motor & TCS relay.
#2 probably is/was the fusible links for the ignition harness
#1 is the solenoid to coil terminal hot wire & that taped up "green" mummy thing could be the TCS relay connector but really can't tell.

 

Get a new forward engine harness about $200.00. Eletrical shorts and fiberglass does not end well. I alway replace rather than try to fix. In pic #2 that is the fuseable link and if its fried you need to solder in a new one, hopefully Bubba didn't hard wire it.

 

TCS is that pre-emission thing that requires the original carb, correct?

If so, I guess I'll be finishing the Bubbafication process since the original carb is long gone and will never be back.
#1 - Cutting both wires away
#2 - Think I'll remove all the tape and clean it up. Probably not cutting
#3 - Going to try to find that plug somewhere (Note: That ground wire you saw was actually my contribution. Needed a temporary ground. I will be rerouting that.)
#4 - Cutting away
#5 - Cutting away

If I cannot remove the entire wire, anyone have a preferred method of making sure the end of the wire doesn't find electricity. i.e. a cleaner version of the mummified wire in pic #1

 

69FASTFUN - I agree wholeheartedly. However, I am not ready to replace the entire harness at the moment. I know it's easier to replace the harness with the engine out, but I'd rather make sure I can connect everything so going to do that sometime after the engine is in and has been running. This will reduce troubleshooting if for some reason the new engine doesn't fire up.

 

HELP (more)!

Oh man, I'm not sure what to do now. I decided to take off the engine harness tape all the way to the driver's side of the firewall. Among other Bubba fixes, I found the male connector to Pic #3, BUT I can't be certain it is the right one. The wires are way too long to make any sense that this is the correct connector. This male connector has one red and one black wire. The red goes thru the firewall and the black wire goes to nowhere. It's disconnected! I have a TH400 and these two wires with the connector could easily reach the tranny. Tranny is being rebuild right now, so I can't reference it to see if there is this type of connector on it. Does anyone know if this type of connector can go on a TH400 or if there is any other place this type of connector goes?

I am now considering a new harness, but the new harness will have all the TCS stuff which I'm trying to take out since the carb is gone. I'd hate to cut up a brand new engine harness. So fixing this harness would be preferred for now.

 

Okay, should've done this first. I tracked the red wire into the firewall. Found that it goes to a switch just on the other side that actuates when the throttle is fully depressed. Some type of kickdown actuator for the TH400? So where does the black negative wire go to?

 

I have searched all over these forums and Googled like crazy. Everyone speaks of a single wire connecting this kickdown solenoid to the switch at the pedal. I have two wires; red and black. Does anyone know where the black wire goes?

 

put an ohm meter on the black wire and on a good ground and see what it does? perhaps for some reason the guy ran a ground to the solenoid?

 

Appreciate the response. Unfortunately I don't have the transmission right now, it's being rebuilt. So all I have is a plug that I'm positive goes to the TH400 with the red wire connected to the kickdown switch and the black wire going nowhere.

From what I've been able to piece together thus far is this black wire is for the TCS which is possible since it is definitely long enough to reach the carb or passenger head. If that's the case, I can just run a single wire down to the tranny since I'm replacing induction with F.I. and the TCS will no longer work. Just hoping to get confirmation. Don't want to cut something I need.

 

Ba-Da-BING! I finally found a pic that shows the two wires and it specifically states the black is part of the TCS (I believe it goes to the carb). So in my case, I'll be removing this but for those of you maintaining the TCS, here's a link to some great information.

Thanks for all of your help!!!

 

Ok, I almost have it. Just a couple more questions please. Please refer back to original post.
