Edited the pics with my crotch in them. lolz. heres the revised version:


Here is a quick how to:

Here are the ECU pinouts and Maft gen 2 pinouts: This is from the 88 manual and is the same pinouts as my 89. Make sure to check the manual for your specific year. The second picture here has the color/ splice assignments here. The AEM stuff applies to the analog gauge like mine.

Once you know where everything is going, go ahead and get started by taking out the glovebox and covers on the passengers side:

Pull down the ECU and pull out the harness from the chassis a little to give you more room to work.

Then unplug the two plugs, and put them so that the clip is down (this is how you look at it to match it up with the FSM diagram), so here i have already cut pin 2 for the maf signal in/out of the maft.

I used crimp connectors and heat shrink. be sure to test all connections by tugging on them before moving on to the next.

I ziptied all of the wires together in a bundle except for the purple, orange, and white ones (for wideband and RPM signal) as they would be going across the dash to the drivers side. Everything else goes to the ecu.

I ran the orange and purple ones to my AEM Uego analog outputs, and ran the white one out through the cruise control grommet along the vacuum line for my boost gauge to the distributor connector. You can get a good, scaled down (under 5 v peak) rpm signal from the harness side white wire on the Distributor plug. **has to be the harness side, as on the distributor side the white wire is not the same one.

If you do it this way, the RPM reads correctly when set to 4 cyl (no more setting to 16 cyl like many have done with the original maft).

Now for initial setup:

If you're like me, and bought one of these used.... you'll want to do a reset on it to clear out the out the previous owners settings. To do this, turn the key to the ON position while holding the upper right arrow for 15 seconds, at first it will say "Hold button to reset!!"

when it resets it will say "all data reset!"

There are several menus. To scroll from menu to menu, hold the upper left button down, and use the arrows to scroll. To scroll through various settings in each menu, hold the lower left button and use the arrows to scroll.

Select your maf IN. (for me right now its DSM1g even though im using the conquest maf) and maf out (for all of us it will be DSM1g). Cylinders and displacement. The maft 2 manual will help you with the rest of the setup / fine tuning.
