roastedpavement.com- Swapping the SR20DET into the Car

After connecting the shift linkage, I realized that there was a problem with the B15 tranny. I could not get the transmission to shift into any gear. I tried a few different things but was not able to get the tranny in gear. I knew I would have to take it back out, pull the case off to see what happened, and run the 99 tranny for the time being. That is what I did.

After that debacle, I was able to resume the swap. It was now time to start connecting the wiring harness and vacuum lines. The first part of the day was spent running out to the parts store and to Lowe's for various items that I needed. Then, when I got back, I began running vacuum lines and routing my wiring harness. First, I just hooked up some long lengths of vacuum hose to the manifold and put them aside. I wanted to run my wiring harness first and then work around that for the vacuum routing.

I decided to mount my MAP sensor using an old bracket that came off the DET when I got it. It ended up working out pretty well. I'm happy with it.

After routing the wiring harness, plugging in applicable plugs, and hiding unused plugs, I came down to the last two plugs on the main part of the harness: the coolant temp sensor plugs. As it turned out, they wouldn't reach. Must be a low port to high port thing. Anyhow, nothing a little wire lead and solder couldn't take care of. Luckily it was only three wires total between the two plugs.

With spindles back on, axles back in, and wheels back on, I set her down on all fours again. I put on the A/C belt, routed/hooked up fuel lines, installed a new cap and rotor, hooked up my boost gauge, and routed/plugged in the MAP harness. The only harness work left is to re-install the alternator section of the harness and the only vacuum work left is routing line to the BCS, BOV, IACV bung (on cold pipe), and wastegate.

After the intercooler install, it was on to the inside where I wanted to finish up wiring the MAP, IAT, BCS, boost control switch, and datalogger switch to my wiring harness adapter. There were wires going all over the place.

It wasn't long and I had them all wired in. Now I simply plug the AEM EMS in and I'm good to go. Here is a shot of my gauges and the rest of the interior after it was buttoned up.

Here are the toggle switches that I hooked up. The red one turns on and off the datalogger and the black one will control low and high boost settings, all through the EMS.
