Thank you for the business, it's very much appreciated!

Now that you are using the Moates.net G1 adapter, and 27SF512 Flash Chip (with ZIF Socket), you are only $85 away from being able to burn your own chips with a Moates.net Burn 2. https://www.moates.net/burn2-chip-pr....html?cPath=64

Ok, I have ecm mounted under the dash and all of my wires ran with the exception of the aldl connector. I need to know what wires go where on the actual connector from the ECM. Diagram anyone??

[dave w]

There are only three wires needed on the '7747 ALDL connector, Pins - A, B, and E.

Pin A - Chassis Ground
Pin B - Goes to ECM Pin A9 - Diagnostic Enable
Pin E - Goes to ECM Pin A8 - Serial Data

Is the aldl for 7427 ecm wired the same way?

The '7427 is different.

Pin A - Pin A1 / Chassis Ground
Pin B - Pin A14 - Diagnostic Test
Pin M - Pin F9 - Serial Data

Ok, I got everything wired n fired, cel is on & it's running rough. I plugged the solus pro in and it's not communicating. Any ideas?

With the 7427 PCM make sure you are entering in a 94-95 c/k automatic truck in the Solus Pro.

Ok, I was using 94 but manual trans, could that be it?

[brian617]

Yep, has to be automatic transmission (PCM), manual trucks use older ECM.

SWEET!!! thanks Brian. I'll try it again tomorrow or next day

Ok, 1st I want to thank you Brian. 94 w/auto worked!! I scanned the ol girl and got a dtc 54. Seems to run ok (@ idle) but I cleared the codes and it came right back. According to the solus it's a fuel pump relay issue, but like I said it starts right up and idles fine, even takes acceleration

[brian617]

Glad I could help. I don't see that DTC listed here http://www.gearhead-efi.com/Fuel-Inj...Information-0D post #5. Can you give me the actual code description the Solus lists? I have access to ShopKey, but it would be Monday before I could look it up.

[ta2ed]

You helped a bunch, I appreciate the hell outta it! I figured out my dtc I didn't hook the fuel pump signal wire in on my relay. B2 is signal wire, monitors voltage to the pump. I will hook it up after work today and all should (theoritically) be good lol
