Thanks for the info and the link, it helps out greatly.

This is such a good thread, I hope that this info helps someone else.

Ok, my bad - I don't think the read the post correctly (or understood it) - but I do now and see the issue. I have always wired it according the MetriPak pinout and never really paid any attention to the actual wiring diagrams much. I will make a note of this in the first post.

Thanks for pointing that out.

I probably would not have noticed it either, but on the schematic the D5 was fuzzy and I couldn't tell if it was a '5' or a '6', so I went to the pinout............

Good thread, quite the asset for the Fiero Community.

Thanks for the help.

Another question, this time concerning the speedometer conversion circuit......

I have seen and used diagrams very similar to this when wiring up the VSS on the 4T65E-HD used on the 3800SC - the circuit is the same except for the diode on the switched 12v lead (C203F).

Is the diode needed in the circuit when doing the 4.9/4T60E swap?

Thanks for the help.

Edit to remove link.

Link doesn't work.

To answer the question though I have never needed to use a diode in this circuit. Just the one .1 uf capasitor, the 22k resistor, and the 1k resistor. The diagram in the first post is correct as far as I know and should work for all engine swaps (unless you have non-fiero gauges).

Another question as I finish the wiring (and my notes) for this 4.9/4T60E swap into an 88 Formula -

Neutral Safety Switch - 7 connector plug - Terminal 'C' - lt grn/blk wire

Per the 'Auto trans Gear Selector SW' graphic on the first page of this thread, this terminal is described as 'Brake SW' and indicates it is hot in Park.

Where does this wire terminate?

Thanks.

DUH!

I figured it out - it's the signal to diengage the parking brake on the caddy - it's not needed in the swap harness.

Mystery solved. Where are my wire cutters?

These are specifically for a 92' 4.9 single O2 into an 87' Fiero Gt Manual. Hope they are of use to someone. This is the second iteration and I have worked out the bugs but as always use at your own risk.
