88 2.3 N/A to 93 2.3 N/A conversion issue

Long story but I wrecked a 93 I had it. Sold it to a co worker who needed a 2.3 for his dad's 88 convertible. He knew about the conversion needed, being completely different electronics. Well a month later he did it. Runs great. Almost everything works. Almost....

Now my reason for bringing this up. The ball joint broke and he wants rid of the car. So in an hour i'm picking up a nice dual plug 88 convertible stang for $175.

Now to it's issues...

1) tach does not work. I have a spare 93 cluster i'm hoping will work.

2) Idles high. If you unplug the IAC it runs idles fine but stumbles a bit.

I have a haynes manual but the 4cyl diagram is on;y for the older motors, not the DP motors.

Anyone have this diagram?

Well I just got the car home. It can't be that hard to do becuase the kid who did the conversion is a complete moron.

I'm haveing issue with idle right now but up inspection I am finding about 5 plugs not hooked up. I'm in search of a scuematic (sp???) for the DP engines.

Basically what he did was rip out the wiring from the 93 and put it all in the 88. The only splicing from what it looks like is the tranny. Not sure why yet. (A4LD)

Your best of doing the whole swap. I'll post pics on Sunday when I get a chance.

PM me and we can talk about it or AIM me at "TheNoachSHO"

In any case any one have the electrical diagrams for 90-93 4cyl. Haynes does not cover them.
