When it’s time for you to tackle the wiring portion of an LS engine install, you will quickly find out that there are a ton of options out there these days. Many manufacturers have stepped up to produce wiring kits for the latest small block technology, so you will have to choose what best fits your project. Today, we are going to be wiring our LS3 project using Holley’s Dominator EFI Vehicle Management Systems, which are intended for all engine applications; from street to unlimited high-end racing operations.

The Dominator systems have nearly unlimited capabilities to control any power adder, input, or output you can throw at them. Need to run a turbocharged, nitrous injected 8-cylinder running water methanol injection? No problem, thanks to the Dominator EFI. How about control on a 4L60E transmission as well as the fuel and spark on your lowrider? Again, no problem! There are alsso enough inputs and outputs to allow the Dominator VMSs to serve as their own data acquisition and control modules. The Dominator VMS will eliminate the need for additional controllers as they are all contained within this one unit.

So follow along, as we install this plug and play wiring kit from Holley in a couple of hours.

<strong>1</strong>. Holley's Dominator EFI Vehicle Management Systems are intended for all engine applications.<strong>2</strong>. This LS3 was ready to have the Holley ECU control unit installed and after seeing other set in place, we knew it would be a fairly easy install for us.<strong>3</strong>. This kit was properly labeled, which made it easy to hook up.<strong>4</strong>. All of the plugs snapped in place and made the connection easy. As you just follow the cables, they start to fall in place.<strong>5</strong>. Here is a look at how the wiring kit will look once it is installed.<strong>6</strong>. The main harness is now labeled and ready to be routed and plugged in.<strong>7</strong>. The wiring began on one end of the engine and will all fall into place. We can't emphasize how easy this kit is to use in comparison to some of the kits that are out there in the market.<strong>8</strong>. When wiring the engine, you might need to lift your car up in the air so you can plug in some of the sensors, including the crankshaft sensor, as this will also allow you to plug into the transmission.<strong>9</strong>. To make sure that your engine runs correctly, you will need to add these oxygen sensors to the exhaust.<strong>10</strong>. Since we knew that the engine was going to be fuel injected, we had the crew weld the oxygen bungs to the exhaust.<strong>11</strong>. The sensors were tightened with room to spare, so you know there will be room to remove it when it is time to replace them in the future.<strong>12</strong>. This sensor was in and ready to read the air mixture, telling the computer how much fuel it needs to burn.<strong>13</strong>. The transmission harness was ready to be installed.<strong>14</strong>. The speed sensor on the transmission was the first thing that needed to be connected from the harness.<strong>15</strong>. The Lokar drive by wire gas pedal was mounted and ready to be plugged in.<strong>16</strong>. There will be a few ways to route your wiring into the designated area. Some cars, like this one, have a panel that you can use to route your cables through.<strong>17</strong>. The ECU is compact and has plugs that plug in.<strong>18</strong>. You will need to find a location to mount the ECU. In our case, we chose to put it under the dash and on the inner firewall to allow us to run our wiring to the box.<strong>19</strong>. The ECU was all plugged in and we were ready to fire up our engine.<strong>20</strong>. This engine was ready to roll using the Holley Fuel Management system!
