Frequently Asked Questions

What do I need for an M52TU, M54, S54, M62, M62TU, S62 swap?

All of these engines (M52TU, M54, S54, M62, M62TU, S62) will need their specific Engine harness, DME, and matching transmission/o2 harness.  They will need the complete harness combination (main engine harness, transmission/o2 harness, and ignition coil harness).

Will the M54 Swap harness for e30 allow for A/C operation?

You should be able to use your original E30 wiring. However, if you experience stalling when coming to a stop while the A/C is on, then you will need to use an additional A/C module. We can offer these modules. Send us a message for more info about these modules.

Will the M54 Swap harness for e36 allow for A/C operation?

For the larger harnesses (M52tu, M54, S54, M62tu, & S62), you will need to use an additional A/C module. These controllers will allow the A/C to function normally. We can offer these modules. Send us a message for more info about these modules.

Will the S54 swap harness for E36 retain use of the following: Original Cluster, Speedometer, OBDII port, AC, Cruise, and Check engine light?

The following will not function: cruise control, check engine light, and the fuel economy gauge. The rest of the cluster will function like normal. A/C can be kept if using our extra A/C module. Send us a message for more info about these modules.

We can provide instructions for getting the cruise control to work.
