For sale - A custom swap harness for a 2.8/3.1/3.4 PR running a 7730 ECM. This is a cleaned, re-worked, no connectors broken harness that is totally plug and play.

New heat resistant tape applied.

The harness will be made for your particular application, MT, AT or whatever.

I can also convert your existing harness. I am willing to do "core charge" swaps meaning I would send you a pre-built harness and you can send me your 'core harness' within 30 days.

Also available are 7730 ECMs and custom EPROMs for the swap.

Pricing

$300 - Labor to tear down, replace connectors and convert a harness
$20 - Shipping
$45 - Core harness charge. Core harnesses must be complete, not cut, and have 4 or less broken connectors.
$40 - Digital Cruise Wiring (requires some user wiring modifications at the location of the original cruise control under the carpet)
$45 - Price for me to supply a working tested digital cruise control unit with proper throttle cable.
$75 - Price to supply the 7730 ECM including 6 cylinder MEM/CAL (it still needs a EPROM)
$65 - Conversion EPROM - VATS disabled, unused options disabled. Available only for 2.8 stock tunes. Custom tunes not available.

hmmm....

May be taking you up on this...gonna try swapping the altenator first to see if that fixes some issues...

You'd be golden if you had the plastic brackets to mount the ECM to the firewall as well.

I have one more 87-88 ECM tray - $40.00 shipped USPS to the US.

My harness is awesome.

Thanks! Glad to hear the comments!

Bump

Openings coming up for any of the harnesses

Do you have a picture of a finished 2.8 to 3.4 harness to judge the quality of the work. I'm interested in one for a 3.4 with automatic. I have the harness core to send.

Dick

got my harness for a 3.4 TDC great work harness looks awsome cant wait to get it in

Seeing your shop you only send products to within USA?

I would have interest in a mod chip to send to Europe (2.8 V6 ECM PROM Chip EGR Delete)

Thanks 701

dont have pictures as it was so wasy to install took me 30mins after i moved a few things for my application.

comes looking brand new. every connector is clearly marked to what sensor it goes too. well worth the price for those of us who cant do wiring. (color blind)

<BUMP> cause it's a cool thing.

I will sure jump on this once i get all of my issues fixed first... good move to make it easier as i am color blind----

So its really not that hard to change out? I always wanted to do the 7730 swap for the improvements, but was concerned about how hard it was to remove the old harness. My current ecm is usually well behaved but it does enjoy a good idle surge every now and again.

Bump -

7730 w/ MEM/CAL available.

Pigtails included if you wish to purchase just a 7730 w/MEM/CAL and make your own swap harness.

Interested in the ECM. I don't need a harness or pigtail, just the ECM with a v6 memcal. Email me a price. kevincdennis@gmail.com

$50 - ECM (w/o MEM/CAL)
$25 - V6 MEM/CAL
$50 - Socketed V6 MEM/CAL

GM MEM/CALs have the PROM soldered in place. My socketed MEM/CAL allows you to use a programmed PROM without needing the adapter. The socket is a standard PROM socket. With the socketed MEM/CAL you can use the stock 27C256 chip , the 27C512 or the SST 27SF512

---

Here is the adapter that you don't need if your MEM/CAL already has a PROM socket on it - http://www.moates.net/g1-me...adapter-tpi-etc.html

---

V6 MEM/CAL - The knock board (the half of the MEM/CAL that isn't the PROM) needs to be matched up with the knock sensors of your engine. V8 7730 MEM/CALs use a different knock board

---

27C256 - The stock chip in the MEM/CAL. Erases under a UV light.
27C512 - A larger PROM that will work in place of the 27C256. When programmed, the data needs to be placed in the upper half of the PROM. The chip erases under a UV light.
SST 27ST512 - The chip most programmers use to directly replace the 27C256. The chip is easier to reprogram because it is electronically erasable. Again the chip when properly programmed to replace the 27C256 has the data placed in the upper half of the chip.

ECM sold to me

Shipped, but I still have more in stock.
