Beta swap ECM pinouts

To use the Accent harness with the Beta 2 engine and ECM you need to rearrange the pinout order at the ECM plug. I have figured out an easy way to get at these little wires, no more cutting and soldering (for the most part) wires that is extremely time consuming to do. Now you can free the wire, pin and all.

02 1.6L manual on the left, 00 1.5L manual harness on the right. Although very different on the engine bay side with wires taking different routes, all wires land in almost the same place with the same plug minus maf and map.


The AMP style ECM plug that many Hyundais used.


Slide this cover up on off, its on there tight.


Remove the 2 yellow clips on both sides of the plug, I used a small flat head screwdriver.

http://img.photobucket.com/albums/v6...s/100_5276.jpg
This side is the small clip side only effecting the five larger pins, I have not yet figured out how to free those yet.


With the large clip out you can now free the bulk of the wires.


Look close, every other pin is numbered, to free the wire simply press the tab down, seen there on the right hand side of the plug, and pull the wire out.

Now you will need to re order the pins to mimic your ECM requirements. I have a few pin outs listed below to help, I will expand on this further at a later date.

Now for the Engine bay side, I am going to quote info from jsharptooth91 and his walkthrough. He swapped in a beta 2 (02 Elantra) and used his 1.6L harness (and ECM but that irrelevant) and this is what needed to be done on the engine bay side.
Beta wiring.

When you go to make your connections, make sure they are good connections. I solder them on and have shrink wrap over the connections. This makes for a good connection.

It’s not a whole bunch of wiring changes. We will be using the 1.6L DOHC ecu. It has the same sensors as the beta 2, except the crank sensor we already replaced. The ecu pin out is the same on the 1.5 as the 1.6 except the 1.5 has a MAF and the 1.6 has a MAP.
Here is a diagram of the two sensors.

If you look at the MAP sensor you will see it has numbers on the outer casing 1-4.
If you look at the MAF sensor you will see it also has numbers 1-5. You have to look down inside where it connects to the connector.
Now just match up the corresponding number to the diagram above, it’s that simple.
The connections below I had to relocate, either making the cables longer or shorter. When you go to plug them in or try to you will know if you will need to extend the cable or shorten it up.
• TPS sensor.
• Coolant temp. sensor.
• IAC
• Wire for the oil pressure sender.
• O2 sensors. I did both. Depending on where your O2 bungs are located.

I think that its, I’m going off of memory, so if I forget something I’m sorry.

I used the Beta coil pack. They have different connectors than the Alpha. I don’t have color match ups, but it will work this way. Do one at a time. On the connector you have a big wire and small wire. They are the same on the Alpha (big & small). Cut of the connector leaving your self some extra wire to do the soldering. Now connect the harness big wire to the big wire on the (Beta) connector and the small wire to the small wire. That’s it! Make sure you do them one at a time, so you don’t get the firing order messed up.

Here are some abbreviations for the pinout breakdowns below
acs = accelerator sensor
ccv = canister close valve
cel = check engine light
cmp = camshaft position sensor
cps = crankshaft position sensor
cpv = canister purge valve
dlc = data link connector
dmtl= diagnosis module for tank leakage
ect = engine coolant temp sensor & sender
ftp = fuel tank pressure sensor
isa = idle speed actuator
kns = knock sensor
maf = mass air flow sensor
map = manifold absolute pressure sensor
tcm = transmission control module
tps = throttle position sensor

LC/LC2 00-05 Accent 1.5L/1.6L Manual/Automatic

I compared the ECM wiring schematics from 3 different years, 2000-2002-2005 and 1.5L/1.6L together and for the most part every pin at the ECM is the same with LC2 using an extra wire at the #11 pin, . There is a differance in some of the wire colors on the LC2, the pinout below is the wire size and color code for 2000-02 LC Accents.
