Fieroseverywhere you have this C225 in the engine bay? I have purchased a 1987 Coupe for my 4.9 swap. I had already purchased me an 87-88 ECM tray. I have all the wiring diagrams.

I took the picture from the other guys thread.

I usually cut that out. If you cut the wires right at that block, most of the wires will be long enough to reach the ECM in the stock location (provided you remove all the tape and reorganize them, there are only a couple of wires that need to be lengthened) - I wire the car in such a way I can remove the engine harness the same way as the stock Fiero one (unplug the ECM, C203 and disconnect the grounds and pull though the bulkhead).
BTW - here is the picture of my ECM (the thing taped to the front is my passkey bypass) - also the white plug near the C203 is for my cruise control (4.9 controlled):

Yes. I used the fiero passthrough for the firewall. The C225 is bolted to the firewall on one of those tabs I no longer needed.
Here is a pic before loom and such..
I just unbolt that connector to remove the engine. My engine harness is actually 2 pieces just like the original caddy one.[This message has been edited by Fieroseverywhere (edited 04-28-2009).]

The great auto axle debate:

OK guys....on this axle thing...Here's what I used. It's 3 years and 4000 miles later on the swap, and all is well. Anyone is welcome to come and drive it if they like...
LH Axle... 1993 Oldsmobile Silhouette. Autozone part # 026838 - 9571
RH Axle... 1993 Oldsmobile Silhouette. Autozone part # 026839 - 9572
Change the OUTER ends for those from stock Fiero axle ends from a MANUAL transmission car. Simple to do, takes 5 minutes per axle. Your new axles will bolt right up just like they were made for the car.

I don't know what else will work....but I do know that this combo WILL work.

It's pretty obvious that a drop-in Pontiac 6000 axle for the left side is easier and cheaper than swapping a Fiero CV joint onto a minivan axle. Rockcrawl recommends the Pontiac 6000 axle for the left side. Nobody on PFF has reported a problem with the Pontiac 6000 axle.

1. In this picture there is a green connector,to the left side of the alternator. The wire goes in, then out of the green part. Then ends up plugged into the alternator in a black plastic plug. Whats the green connector for? Where does it connect to? I cant find reference to it in my wiring diagrams. I borrowed Mickey Moose's picture:
2. All of these "Cruise Control" wires and connectors, can I just clip them out of the harness as I am not going to use these.

IIRC the green plug only has the on wire in it on the one side - this is used for grounding out the alternator to disable it during the proceedure to set the timing.
If you are NOT using cruise, you can remove them from the harness - for unused wires on the ECM plugs I just grab them and yank the pin out of the plastic connector. ONLY DO THIS after you have started the motor and it is running, the pins are damaged when you do this and can not be put back in. But feel free to yank the cruise wires, just double check before you remove them.

Great information. I had run into a little snag on my harness yesterday. My 93 engine still had its injector wiring part of the harness on the injectors. My 91 harness uses two connectors, one for the even bank, and one for the odd bank. The 93 only has one connector on the injector group harness for all 10 wires. I still had 90% of the 93's harness in the garage, and I think I can splice in the 93 injector connector part into the 91's engine group wiring harness. There was only one difference in the color of the wiring to deal with. I had access to the 92-93 wiring off of your thread from FieroAddiction, and Alldata.com, as well as the available 91's harness diagrams. I am gonna lay all of this out on my 4.9 Wednesday morning, and get this all sorted out in a neat and orderly fashion. [This message has been edited by josef644 (edited 06-22-2009).]
