Cardiovascular System

 

You need to buy four 4 pin relay, and 6 fuse holders with 10 amp fuses, or a small universal fuse box. I got mine from Radio Shack.

 

Next you need to find the 3 connectors on the S13 harness. They'll be in the same location as the s12 plugs were at. Follow the S13 harness from the ecu until you see 2 small canister shaped things with rubber caps. one has a yellow wire with a red stripe. Find these then move along to the 3 connectors. Unplug these and then you will have disconnected your engine/ ECU loom.

 

Now your ready to wire your relays/ fuses.

 

1st relay: ECU Power

 

Pin 30- 12v constant on "Fused" power source

Pin 87- Black/ white wire from S13 harness

Pin 85- Ground

Pin 86- Ignition on source

 

2nd relay: Ignition

 

Pin 30- 12v constant on "Fused" power source

Pin 87- Bigger black/ red wire spliced with bigger blue/ red wire from S13 harness

Pin 85- Ground

Pin 86 Ignition on source

 

3rd relay: IACV

 

Pin 30- 12v constant on "Fused" power source

Pin 87- black/ yellow wire from S13 harness

Pin 85- Ground

Pin 86- Ignition on source

 

4th relay: Fuel pump

 

I re-wired mine completly using the following diagram:

 

 

Next

ECU relay- Wire the red/ black wire from the S13 harness to an ignition on source

 

ECU back-up power- Wire the red wire from the s13 harness to a 12v constant on "fused" power source

 

O2 sensor- Wire the brown wire from the S13 harness to an ignition on source

 

Next move on to the S12 lower harness. I simply just plugged back in the tranny connectors from the s12 lower harness since I used the s12 b tranny.

Oil sender- Use the S12 sender and S12 plug still connected to the s12 lower harness

Alt- MK1: Snip off the s13 alt connectors, and snip off the s12 alt connectors. Next splice on the s13 connectors onto the s12 lower harness, then plug onto the alt.

Alt- MK2: I was informed by Indy that the MK2 ca18et alt wiring is the same as the S13's, so all you have to do is just plug it back in. Not sure on the mk2 ca20 alt wiring.

Starter- I can't remember.....I think the S12 starter wiring from the lower harness, just plugged onto the s13 starter......I could be wrong though.

 

Next move to the ECU side of the S13 harness, which now should be laying in the foot well on the left side.

There should be a small white plug near the s13 ecu....part of the s13 harness.

 

You have to wire in the temp sensor. You will need to remove the instrument cluster.

Find the blue/ black wire from the small white s13 plug. connect a wire to it, and run it up behind the instrument cluster. Next snip the purple/ white wire behind the cluster, which is the temp gauge signal wire, and connect the wire that you ran up to the cluster side of the purple/ white wire.

Next take off the ignition switch cover from around the steering column. Find the yellow/ black wire at the back of the key switch....this is your starter signal. Now find the orange wire from that small white plug on the S13 harness, where the temp signal wire came from. Connect a wire to that orange wire, add a inline fuse, then run it up and splice it into the yellow/ black ignition wire at the back of the key switch. DON'T CUT THIS WIRE, SPLICE IN THE NEW WIRE.



Next down by the s13 harness by the ecu should be atleast 1 black wire. Add some wire to this, and ground it. I had 3 total black wires, and grounded all 3.

 

Wiring the tach. Follow the instructions within this thread..........

I did it slightly different....basically what I did was splice in the 4 diodes on the coil pack wiring near the ignitor, as per Gerry's instructions, then the opposite ends of the diodes I twisted all 4 together, crimped them into a butt connector, then crimped a long piece of wire in the other end of the same butt connector, routed it, and spliced in to the tach gauge signal wire, which is part of the S12 primary transistor wiring harness, down near the maf location. If you removed ALL of your s12 wiring, then you'll have to tap into the back of the instrument cluster as described in the above link.

 

Your wiring is now complete!

Cardiovascular System

 

Part 1. Blood Vessels

 

There are three major types of blood vessels in the body. These are called arteries, veins, and capillaries.

Arteries are the large blood vessels which lead blood away from the heart. Their walls are made of connective tissue, elastic fibers, and an innermost layer of epithelial cells. Arteries are strong enough to withstand the high pressure of the pumping action of the heart. Their elastic walls allow them to expand as the heartbeat forces blood into the arterial system throughout the body. Smaller and thinner branches of arteries are called arterioles. They carry the blood to the tiniest of blood vessels, the capillaries.

Capillaries are delicate, microscopic vessels with only one epithelial cell in thickness. They carry nutrient-rich, oxygenated blood from the arteries and arterioles to the body cells. Their walls are thin enough to allow passage of oxygen and nutrients out of the bloodstream and into the tissue fluid surrounding the cells. At the same time, waste products such as carbon dioxide and water pass out of the cells and into the thin-walled capillaries. The waste-filled blood then flows back to the heart in small veins called venules which branch to form larger vessels called veins.

Veins are thinner-walled than arteries. They conduct waste-filled blood toward the heart from the tissues. Veins have little elastic tissue and less connective tissue than arteries, and the blood pressure in veins is low. In order to keep blood moving back toward the heart, veins have valves which prevent the backflow of blood. Muscular action also helps the movement of blood in veins.
